Pelutils

- `get_repo` now accepts a custom path search for repo as opposed to always using working dir

- `log.input` now also accepts iterables as input

For such inputs, it will return a generator of user inputs

- Added functionality to logger for logging repository commit
- Removed function `get_commit`
- Added function `get_repo` which returns repository path and commit

It attempts to find a repository by searching from working directory and upwards
- Updates to examples in `README` and other minor documentation changes
- `set_seeds` no longer returns seed, as this is already given as input to the function

- Only works for Python 3.7+

- If logger has not been configured, it now does no logging instead of crashing

This prevents dependecies that use the logger to crash the program if it is not used
- `log.throw` now also logs the actual error rather than just the stack trace
- `log` now has public property `is_verbose`
- Fixed `with log.log_errors` always throwing errors
- Added code samples to `README`
- `Parser` no longer automatically determines if experiments should be placed in subfolders

Instead, this is given explicitly as an argument to `__init__`

It also supports boolean flags in the config file

- Readd clean method to logger

- The logger is now solely a global variable

Different loggers are handled internally in the global _Logger instance
