feat: ci pipeline correction (#90)

* fix: removed absolute paths for reference data

* feat: human reference accession number for CI config

* feat: configuration grouping for reference data

* feat: requiring a ref section in the configuration, with only species and accession number

* fix: allowing for additional dots in sample schema to allow for the test data to be worked with

* fix: input directory for test workflow

* fix: typo fna -> fa suffix

* fix: corrected data paths

* fix: changed min_length for CI to 10 and alpha > 1

* fix: more and diffently attributed sample for CI test

* fix: removed outdated commented about p-value correction

* feat: update to qualimap wrapper to v4.4.0

* feat: de analysis does no longer fail, when condition a and b are confused. Also: no volcano for non-significant data

* fix: attempt to run with different input path

* fix: pointing test to workflow profile

* feat: added additional debugging infos for non exsisting files

* feat: added additional debugging infos for non exsisting files - now with format string

* feat: added pwd to debug information

* fix: relative directory in test one level up

* fix: formatting

* fix: removed suffix from sample config

* fix: print existence of input dir

* fix: added directory listing for current dir

* fix: gnarf - wrong namespace ...

* gnarf

* fix: trying with submodule checkout

* fix: fixed typo, bumed checkout versions to 3

* only testing

* again only test

* again full test

* fix: hopefully working sample inference

* fix: added presumably missing submodule

* fix: same correction as before

* fix: same correction as before - now reallywq

* fix: corrected introduced missing return
