Resolve some clippy lints, ignore the rest
`cargo clippy` finishes cleanly after this. I stuck to only what I think are the least objectionable lints: cleaning up useless identity conversions that do `from`/`try_from`/`into` going from T->T, extraneous `&` on expressions that are already a reference, unused lifetime parameters, and similar.
Below in the \<details\> is the complete remaining output of `cargo clippy` with the `allow` attribute removed. I think all the lints left are fine to keep ignoring.

- Changed arg parsing to handle comma seperated list of `u64`'s.
- Changed type and field names of config, executor and global state
to hold a set of tracked ids.
- Adjusted Readme:
- explained list format
- arguments do not overwrite, instead append
- no effect on duplication
- Created a parsing function for comma separated lists
- Added error printing to alloc_id parsing
