In shide: Date/Time Classes Based on Jalali Calendar

shide 0.2.1

Default formatting for jdatetime objects is changed to conform to default R behavior.
jdate and jdatetime vectors are printed more nicely in tibbles.
Rounding family of functions (sh_floor(), sh_ceiling() and sh_round()) now accept multi-unit values for unit argument.
jdatetime() and jdatetime_make() now support ambiguous time resolution strategies via ambiguous argument (ambiguous times occur during a repeated interval when the clock is adjusted backwards during the transition from DST to standard time).
Fixed a bug regarding casting of jdatetime to jdate (#4).

New sh_year_is_leap() determines if a Jalali year is a leap year.
New accessor and replacement functions are added to get/set the components of Jalali date-time objects.
New family of functions for rounding Jalali dates to a specific unit of time:
- sh_floor() rounds a jdate object down to the previous unit of time.
- sh_ceiling() rounds a jdate object up to the next unit of time.
- sh_round() rounds a jdate object up or down, depending on what is closer.
New seq.jdate() generates regular sequences of Jalali dates.
as.POSIXlt() now errors with jdate and jdatetime input. In order to cast jdate and jdatetime to POSIXlt, first, they should be converted to Date and POSIXct respectively.
jdate() now truncates numeric input toward zero before generating a jdate object.
jdatetime() now truncates numeric input toward zero before generating a jdatetime object.
Fixed a bug where names were dropped after calling format() upon a jdate or jdatetime object.
