meryl count assertion failed with large K

[Dmitry-Antipov]

Tried to run with relatively large k (101), got this assertion

meryl count k=101 compress hifi.fasta.gz output 101.hpc.meryl

k=71 seems to work

would be nice to have max allowed k somewhere in usage/docs.

[Dmitry-Antipov]

actually k=71 worked only in the sense that it did not crash. Results are irrelevant
unique 0 (exactly one instance of the kmer is in the input)
distinct 1458 (non-redundant kmer sequences in the input)
present 33707750420 (...)

k=63 provided reasonable results
