Somaticseq

Mostly maintenance
- A lot of coding stylistic changes
- Enforce versioning for some dependencies in setup.py, including python>=3.10
- For XGBoost model, additionally output json file (i.e., decision trees)
- Updated some docker files for 3rd party tools
- remove `-d dbsnp.vcf.gz` parameter from tumor-only LoFreq command (that param is only meaningful for tumor-normal pair)

**Full Changelog**: https://github.com/bioinform/somaticseq/compare/v3.7.4...v3.8.0

ntree_limit is replaced with iteration_range in xgboost.predict in xgboost >=1.4. This release uses `iteration_range=(0, iterations)` instead of `ntree_limit=iterations`.

Allow xgboost hyperparameters be passed into `somaticseq_parallel.py`, e.g., `somaticseq_parallel.py --somaticseq-train --extra-hyperparameters scale_pos_weight:0.1 seed:100`. Previously, they could only be passed into `somatic_xgboost.py`. Beware, however, multi-argument options like `--extra-hyperparameters` and `--features-excluded` cannot be placed immediately before `paired` or `single`, because otherwise it'll try to include `paired` or `single` as an argument instead of invoking `paired` or `single` mode.

- More robustly check sorting order when VCF files are being read. Raise Exception when they are not sorted according to the reference file.
- Change `-u $UID` to `-u $(id -u):$(id -g)` when invoking docker command in `somaticseq.utilities.dockered_pipelines.container_option`.

- Fixed three bugs where dbsnp and cosmic VCF and exclusion-region BED files did not pass properly in `makeSomaticScripts.py`.
- No change in SomaticSeq code otherwise.

Major feature upgrade: SomaticSeq now supports the input of any arbitrary VCF files in addition to the callers we have explicitly incorporated, e.g., via `--arbitrary-snvs callerX_snv.vcf callerY_snv.vcf` and `--arbitrary-indels callerA_indel.vcf callerB_indel.vcf` options for the `somaticseq_parallel.py` command.

Must separate the SNVs and indels into separate VCF files before using them as input to SomaticSeq. If you have a VCF file that has combined SNV and indels, you may use this script included in our repo, i.e., `splitVcf.py -infile combined_variants.vcf -snv snvs.vcf -indel indels.vcf`. Input can be both `.vcf` or `.vcf.gz`. Output will be `.vcf`.

For the "arbitrary input VCF files," calls labeled as REJECT in the FILTER field will not be counted and will be assigned a value of _0_ in the `if_Caller_X` fields. Calls labeled as LowQual will be assigned a value of _0.5_. Calls without any filter label will be counted as a bona fide call for that particular VCF file and assigned a value of _1_, i.e., as though it is a PASS call. So modify your VCF files accordingly if needed.

* This is a special release for the Somatic Mutation Working Group of the SEQC2 Consortium to establish v1.2 of the somatic reference call set, i.e., [Fang, L.T., Zhu, B., Zhao, Y. _et al_.

* This release is based on the older SomaticSeq v2.8.1. It contains many custom scripts specifically designed to complete SEQC2's somatic reference samples project.
* This release is **not** intended for general use.
* No code change, but updated NCBI's new FTP address in the README over the original [commit](https://github.com/bioinform/somaticseq/tree/2c642fc2849d7a9360bd4b1d166b90b3e63ec429). The FTP address for the SEQC2 Somatic Mutation Working Group can be found here [here](https://ftp-trace.ncbi.nlm.nih.gov/ReferenceSamples/seqc/Somatic_Mutation_WG), so navigate there if a file changed its original location.
