GPU acceleration for COMEBin and SemiBin2

[d4straub]

Description of feature

GPU acceleration seepds up binning with COMEBin and also SemiBin2. For SemiBin2 that mostly beneficial when no environment (model) is used and that is the case when multiple samples with abundance information (bam files) are given, i.e. when the sequencing depth of multiple samples is used. COMEBin and SemiBin2 were added without GPU support in https://github.com/nf-core/mag/pull/875 and https://github.com/nf-core/mag/pull/930, respectively.

There are many nf-core modules with GPU acceleration. Here is a PR that adds gpu labels into the template. And here a docu from a nf-core pipeline about gpu usage. Didnt find anything in the nf-core docu though, maybe missed it.
