map2tidy v2.1.1

map2tidy v2.1

Changed the naming of the files (prepending 0's to have always 6 digits: LON_-000.250)
Added a feature to subset certain longitudes only (argument filter_lon_between_degrees)
Made error messages more explicit.

Public release after refactored code
Improved robustness:
- map2tidy can now handle hourly data (using pkg CFtime)
- generally more automatic handling of NetCDF files.
Streamlined API:
- function calls require less user input. Since more information is robustly derived from the data itself, the use of various data sets is facilitated.
- Namely: get rid of input arguments: timedimnam, noleap, res_time
Improved Verbosity:
- map2tidy now reports what it is doing
- map2tidy now suggests alternatives if user input is wrong, e.g. typos or wrong names of ‘longituded’ etc…
- unsolved: when ncores > 1 verbosity remains low, since message() does not get printed from within multidplyr
