coverage is greater than 100

Test kmcp with mock community datasets. The result is like this.

It's reasonable. Similar to sequencing coverage, it means the number of reads aligned to each base or just "copies" of an organism.

$ kmcp profile -h
...

KMCP format:
  Tab-delimited format with 17 columns:

     1. ref,                Identifier of the reference genome
     2. percentage,         Relative abundance of the reference
     3. coverage,           Average coverage of the reference
     4. score,              The 90th percentile of qCov of uniquely matched reads
     5. chunksFrac,         Genome chunks fraction
     ...

Perhaps, the coverage and chunksFrac is a little confusing.

• 3rd column. coverage, vertical coverage of genome.
• 5th column. chunksFrac, horizontal coverage of genome chunks.
