generalize-tsv with (;) separator doesn't work properly

[Sarra-Ouelhadj]

Describe the bug
schemauto generalize-tsv -s ";" data_file.csv doesn't work properly. Same thing with .tsv files with (;) as a separator.

To Reproduce
schemauto generalize-tsv -s ";" eco_ecologie.zfe.csv or schemauto generalize-tsv -s \; eco_ecologie.zfe.csv or schemauto generalize-tsv -s ';' eco_ecologie.zfe.csv
Data file is attached here : eco_ecologie.zfe.csv

Expected behavior
Produce a LinkML model with the different attributes separated in the original file with a semicolon (;).

Additional context
I use Schema Automator Docker Container. The Direct Installation of Schema Automator didn't work for me, issue reported here #111.
