evsim 1.7.2

Bug fix in adapt_charging_features(): Energy could exceed what fits between the connection datetimes, because ConnectionHours was rounded to 2 decimals before capping the charging time while the datetimes are truncated to whole minutes (e.g. 49 minutes at 11 kW gave 9.02 kWh instead of at most 8.98 kWh). Charging time and Energy are now derived from the whole-minute datetimes, and Energy is rounded down to 0.01 kWh.

Replaced multi-core processing from parallel::mclapply() by purrr::in_parallel() using mirai package
Removed mc.cores parameter from all functions since now the parallel processing must be defined by the user
Function adapt_charging_features() now filters incorrect sessions and prints a warning

Bug fix in ConnectionHours calculation
Bug fix in get_demand() and get_occupancy() functions
Bug fix in adapt_charging_features() function: need to convert timezone to UTC to avoid NA in summer time shift

Parameter align_time has been removed from all functions in favour of internal automatic alignment thanks to introduction of function is_aligned.
Changed variable names in expand_session function (NominalPower -> PowerNominal, RequiredEnergy -> EnergyRequired)
Bug fix in adapt_charging_features function: ConnectionHours now rounded to 2 digits to improve accuracy of calculations
Simulated energy using log-normal distribution with a minimum of 1 kWh and simulated connections with a minimum of 30 minute duration, to be more realistic.
Bug fix in get_evmodel_summary()
New legend formatting for plot_ts()
Added parameter n_sockets to function add_charging_infrastructure() to specify the number of sockets per charging point

In simulate_sessions now user_profiles can also be NULL to use the default evmodel config.
Changed get_ev_model to get_custom_ev_model to avoid using auxiliary functions to get GMM from parameters. Thus, the argument parameters_lst has been introduced to directly use all time-cycles parameters, and functions get_connection_models_from_parameters and get_energy_models_from_parameters are now internal and not exported.
Custom models ratio’s in parameters_lst argument of function get_custom_ev_model must be now between 0 and 1 and not between 0 and 100, to be consistent with the evmodel created by evprof.
Introduced power_interval parameter in get_charging_rates_distribution function. It is used to round the Power values into this interval resolution. It can also be NULL to use all the original Power values.
Now plot_ts function plots with the data timezone by default with dygraphs::dyOptions parameter useDataTimezone=TRUE.

Improved the efficiency of get_demand and get_n_connections
Added function plot_ts to plot time-series in a dygraphs HTML plot
Added multi-core processing for Windows distribution
Energy GMM inside of evmodel also contain the ratio of every charging_rate
Function expand_sessions is now exported
Added functions to create summary tables from evmodel object

Improved functions for calculating demand and occupancy (now with multi-core processing)
Included more example data (evsim::california_ev_sessions and evsim::california_ev_sessions_profiles).
Included functions to create a model from Gaussian Mixture Models parameters.

Added read_ev_model function to read an EV model JSON file generated by package {evprof}

Bug fix in the evmodel class printing function
Adding California's EV model as example evmodel (evsim::california_ev_model).
Function "simulate_sessions" now requires a "user_profiles" parameter with the ratio of every user profile and the optional specific power.
Add function "get_user_profiles_distribution" to facilitate the creation of the newly requested parameter "user_profiles" by function "simulate_sessions"
Remove function update_profiles_ratios in favour of prepare_models. This new function is used inside the simulate_sessions function using the sessions_day and user_profiles parameters to modify the evmodel input.
