2.99.1 Standardized usage

New features

• directory structure follows more closely
  snakemake workflow catalog's standardized usage
• configuration manual generated automatically from JSON schema
  see: config/config.html

For legacy V-pipe 1.x/2.x users:

• the new directory structure requires adapting old INI files
  please refer to config/README.md

NOTE:

• currently only the analysis of NGS viral data is fully tested and
  guaranteed stable.
• For other more advanced functionality (e.g., benchmarking) you might
  want to wait until a future release.
