Add support for unique R1 and R2 prefixes in split2

[jdidion]

I'd like to be able to do the following:

seqkit split2 -1 my_r1.fq.gz -2 my_r2.fq.gz --by-parts 10 --by-parts-prefix "my_r{read}_"

And get out:

my_r1_001.fq.gz
my_r2_001.fq.gz
my_r1_002.fq.gz
my_r2_002.fq.gz
...

Thanks!

Oh, It looks like a bug!

fixed:

$ seqkit split2 -1 my_r1.fq.gz -2 my_r2.fq.gz --by-part 10 --by-part-prefix "my_r{read}_" -O out
