upgrade fibertools-rs version

[cademirch]

Currently we use fibertools-rs=0.6.0

FIRE/workflow/envs/env.yaml

Line 10 in fd019e5

- bioconda::fibertools-rs==0.6

We just released 0.9.0 and should bump this. Some changes that need to happen here:

• update any ft pileup commands because its CLI changed regions from positional to flag -r in fiberseq/fibertools-rs@099b8f4
• Possibly use new call-peaks subcommand?

I do want to do all of this. Maybe in steps. Call peaks will need to be saved for a major release I think.
