create FST LEXC files from database

[dwhieb]

Create the FST LEXC files from the ALTLab database.

The current scripts that convert the TSV version of CW to LEXC lives in the lang-crk repo.

• https://github.com/giellalt/lang-crk/blob/develop/tools/shellscripts/wolvengrey-toolbox2fst-tsv.sh
  • adds (tentative) FST stems and prepares it for conversion to LEXC
• https://github.com/giellalt/lang-crk/blob/develop/tools/shellscripts/wolvengrey-new2lexc.sh
  • converts CW TSV to LEXC

Generating the lexc files will remain at the lang-crk repo for the time being, with code in the private altlab/ repo.
