Feature request: seqtk seq: multiline to single line Fasta

[oschwengers]

Hi, thanks for the great tool! I use it regularly and have incorporated it into many pipelines and workflows.

What do you thinks about a new seqtk seq option in order to wrap multi line fasta files into single line files?

Example:

>foo
atcgactgatg
ctagtcatgctg
gat
>bar
tagctacgttac
gattcga

would become:

>foo
atcgactgatgctagtcatgctggat
>bar
tagctacgttacgattcga

I do this very often to preprocess and filter huge fasta files. I guess this would be a nice feature for many people and implementing it shouldn't be a tough task... Thanks a lot!

You need to update seqtk. seqtk seq outputs single line from at least 2 years ago.
