Praat version validation fails if no patch version

https://github.com/santiagobarreda/FastTrack/blob/fc20bd32ca92f7ae47d5d65a4c5f7178d7af78e4/Fast%20Track/functions/utils/importFunctions.praat#L31-L36

This fails if praatVersion$ is (e.g.) 6.4, in which case versionPraat is parsed as 6.

I'd suggest using the more robust version-checker I just wrote: https://github.com/djvill/hwttiwtot/blob/main/Praat/ParseValidateVersion.praat
