Add support for [X] cigar string on agat_convert_minimap2_bam2gff.pl

[eggrandio]

I am using .bam files created by pbmm2. This minimap2 wrapper uses the --eqx minimap2 option by default.
When I try to convert the .bam file to .gff, I get the following error message:

Are there plants to support cigar string [X] ?
