GPU version has corrupted sequence output

[yab-fsp]

Expected Behavior

For the GPU version, when running easy-search mode and using --format-output with "tseq" to get the sequences for the hits, the amino acid sequences should be printed properly.

Current Behavior

Instead, the amino acid sequence appears as a bunch of other characters (see below).

Steps to Reproduce (for bugs)

Comandline: mmseqs easy-search $INPUT.fasta /mnt/ephemeral/dbmm/nr_gpu RESULT /mnt/ephemeral/tmp2 --gpu 1 --num-iterations 3 -s 8 --max-seqs 999999 --format-mode 4 --format-output "query,target,evalue,fident,nident,qstart,qend,qlen,tstart,tend,tlen,alnlen,bits,qcov,tcov,tseq"

MMseqs Output (for bugs)

[milot-mirdita]

Good catch, I did not think this through completely. It's not actually corrupted, this is the new byte encoding necessary for the GPU search (with byte values 0 to 64 encoding masked or unmasked amino acids). I will fix the display issue asap.
