cmap parameter added to configuration file

Added user-defined cmap option to configuration file.

Note, the config.ini file is initialized the first time ragu is run on a computer, so if you've previously run ragu, you'll need to do one of three things to implement this change:

1. add the following two lines directly under the 'param' key

# str cmap: Matplotlib colormap to use (default = seismic)
cmap  = 

2. Regenerate your config file

import os
from ragu import config
# get configuration file
basedir = os.path.join(os.path.expanduser('~'),'RAGU')
config.create_config(basedir+'/config.ini')

3. Remove your existing configuration file, and then a new one will be generated upon running ragu

Several small changes since last release

Release incorporates all changes from ragu-0.1.27->ragu-0.1.40

RAGU is pypi installable

Several changes since last release.

1. RAGU has been slightly been restructured so that it can be installed via pypi
   $ pip install ragu
2. All pyproj coordinate transformations updated to pyproj2 format

RIMFAX ingester added

RAGU can now ingest RIMFAX data from the MARS 2020 rover - however PDS datafiles must be first parsed into separate files for the shallow, surface, and deep modes. Example code below and included in ingest/ingest_rimfax.py:

#  data files should first be split up into separate files for each mode of active sounding - use the following commented code to do this:
mode=[26,78,214]
name=['shallow','surface','deep']
for fn in glob.glob('rimfax*.csv'):
  f = pd.read_csv(fn, header=0)
  for m,n in zip(mode,name):
    f_ = f.loc[(f["record_type"]==0) & (f["config_id"]==m)]
    f_.to_csv(fn[:-4]+'_'+n+'.csv')
