moved input_files into top-layer test directory for consistency.

corrected removal of test files

- renaming bedgraph
- creating ALFA qc plots

removed conda dependence, moved import statement.

included ALFA in finish rule, corrected annotation.gtf and config.yaml, created new .svg

- log and, if workflow is executed on cluster, cluster log directories are explicitly created in `Snakefile`
- location of main log directory can be configured in `config.yaml` (field `log_dir`, previously: `local_log`; requires change in script `labkey_to_snakemake.py` as well as subworkflows as field name is hard-coded there)
- location of cluster log directory can be configured in `cluster.json` (in field `__default__` -> `out`)
- `config.yaml` and `cluster.json` in `tests/input_files` are set such that a directory `logs/` is created in the directory where Snakemake is run (i.e., the directory of each test); cluster logs are stored in a subdirectory `logs/cluster`
- removes instructions to explicitly create log directories from docs and all test scripts
- cleans up main `Snakefile` (apart from Snakemake-specific syntax, now passes `flake8` linter test)

- add script that prepares Snakemake input files 'samples.tsv' and 'config.yaml' from LabKey table
- script either connects to API directly (with '--remote' and related options) or processes a tab-separated LabKey dump file
- add tests for both use cases
- common input files for tests now in 'tests/input_files'
- update all other tests to account for new file locations
- update documentation
