tabs in fasta headers

[katholt]

From Corin:

I think there might be a bug in Kleborate when FASTAs have tab characters in their header. I get the following output with the attached FASTA, but if I remove all the tab characters it runs correctly.

`Error: Kleborate failed to run
Command: ['kleborate', '-a', '/tmp/query.fna', '-o', '/tmp/', '-p', 'kpsc']
Return code: 1
Standard output: strain species N50 ST virulence_score resistance_score num_resistance_classes num_resistance_genes

Issue arises from: https://github.com/klebgenomics/Kaptive/blob/8c4516fd282efa743887a539f7ab7cf9e5bbe411/kaptive/assembly.py#L100
Need to replace split(' ') to a straight-up whitespace split (on first instance).
