Pelutils

- `Parser.parse` now returns only a single experiment dict if `multiple_jobs` is False
- Improved logger error messages
- Added `Parser.is_explicit` to check if an argument was given explicitly, either from CLI or a config file
- Fixed bug in parser, where if a type was not given, values from config files would not be used
- Made fields that should not be used externally private in parser
- Made `pelutils.ds.unique` slightly faster

- Commit is now logged as `DEBUG`
- Removed `BatchFeedForward.update_net`
- `BatchFeedForward` no longer requires batch size and increase factor as an argument
- Removed `reset_cuda` function, as was a too small and obscure function and broke distributed training
- Added `ignore_missing` field to `DataStorage` for ignoring missing fields in stored data

- Fixed bug where TickTock profiles would sometimes not be printed in the correct order
- Removed `TickTock.reset`
- Added `__len__` and `__iter__` methods to `TickTock`
- Added option to print standard deviation for profiles
- Renamed `TimeUnit` to `TimeUnits` to follow `enum` naming scheme
- Time unit lengths are now given in units/s rather than s/unit

- `TickTock.__str__` now raises a `ValueError` if profiling is still ongoing to prevent incorrect calculations
- Printing a `TickTock` instance now indents percentage of time spent to indicate task subsets

- Added `subfolder` argument to `Parser.document_settings`

- A global instance of `TickTock`, `TT`, has been added - similar to `log`
- Added `TickTock.profile_iter` for performing profiling over a for loop
- Fixed wrong error being thrown when keyboard interrupting within `with TT.profile(...)`
- All collected logs are now logged upon an exception being thrown when using `log.log_errors` and `collect_logs`
- Made `log.log_errors` capable of handling chained exeptions
- Made `log.throw` private, as it had little use and could be exploited
- `get_repo` no longer throws an error if a repository has not been found
- Added utility functions for reading and writing `.jsonl` files
- Fixed incorrect `torch` installations breaking importing `pelutils`
