Update metabat2 output channels and compression (#1111)

* feat: each output type has dedicated channel replace bgzip with gzip can only zip one at a time

* Add condition moving of unbinned files

* fix: solution for moving sometimes non-existant files

* fix: update meta.yml to add the new channels

* fix: remove most of the checksums due to variability

* fix: tweaking of output

* Update modules/metabat2/metabat2/main.nf
