- fixes some functions in `labkey_to_snakemake.py`
- add optional argument for trimming polyA tails; they are trimmed as follows:
  - if mate is sense, oligo-A is added to sample table for `cutadapt` rule to trim
  - if mate is antisense, oligo-T is added to sample table for `cutadapt` rule to trim
  - if option is set to `--trim_polya`, oligo-X stretch is added to sample table and `cutadapt` will not trim

- 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)

- trap call functionalized through cleanup() function
- function added to all test scripts
- function prints out exit status of last command before trap
- flag `--verbose` added to Snakemake calls in all test scripts
- script tests rename to follow naming convention 'test_script_<script_name>_<script_run_mode>
