AGAT can now be used with perl >=5.36
AGAT::AGAT is playing a central role. Scripts load this module and then all others are loaded by it because all other modules use :

sub import {
 AGAT::MODULE->export_to_level(2, @_); # to be able to load the EXPORT functions when called from one level up;

but since perl version 5.36 it does not work anymore. To fix the problem I removed the export_to_level statement from other modules and tell explicitly to AGAT::AGAT to load functions from theses module using:

sub import {
    AGAT::AGAT->export_to_level(1, @_); # to be able to load the EXPORT functions when direct call; (normal case)
    AGAT::MODULE->export_to_level(1, @_); # to be able to load the EXPORT functions when direct call; (normal case)
}

• Fix AGAT not working in perl 5.38 #416 AGAT compatible with Perl 5.36 ? #392
• add dockerfile for AGAT with perl version 536 for test purpose
• add test for perl>5.36 in CI
• add missing semicolon in agat_sp_load_function_from_protein_align.pl
