Merge branch 'fix-flexiprep_noext' into 'develop'
Update filename + extension retrieval in Flexiprep Two changes: * Refactored the uncompressed filename + extension retrieval. Also made sure now that extension trimming is case-insensitive (".gzip" and ".GZIP" are both trimmed). * Added a clearer error message when the input file doesn't have any extension.
