Fortran 77 Comment Parsing Issue with Initial 'C' Character

[Foadsf]

Describe the bug
Hello i-CodeCNES team,

I've encountered an issue with the Fortran 77 analysis in i-CodeCNES where lines starting with the C character are not recognized as comments. This happens even when explicitly specifying the language using the command:

icode.bat <FILE> --checked-languages "Fortran 77"

Expected behavior
In Fortran 77, any line starting with a C or c in the first column should be treated as a comment. (reference)

Current Behavior:
Lines starting with C are not considered comments by the analyzer, leading to potential misinterpretation of the code structure.

Temporary Workaround:
A temporary workaround is to replace all starting C characters with ! to ensure they are recognized as comments by i-CodeCNES.

Suggested Fix:
It would be beneficial to update i-CodeCNES to correctly recognize lines starting with C as comments when analyzing Fortran 77 code.
