Add options for different compression levels for parquet files

[tomjholland]

This pull request includes several changes to the pyprobe project, focusing on adding new functionality for compression options and refactoring the code to improve clarity and maintainability.

New Functionality:

• Added support for different compression priorities (performance, file size, uncompressed) when converting files to PyProBE format. ([[1]](https://github.com/ImperialCollegeLondon/PyProBE/pull/153/files#diff-441aec132d927ef70cd9824112874874d1fb11d9d8bc0604c3b492ed3ad9a7c8L64-R110), [[2]](https://github.com/ImperialCollegeLondon/PyProBE/pull/153/files#diff-441aec132d927ef70cd9824112874874d1fb11d9d8bc0604c3b492ed3ad9a7c8R122-R207), [[3]](https://github.com/ImperialCollegeLondon/PyProBE/pull/153/files#diff-441aec132d927ef70cd9824112874874d1fb11d9d8bc0604c3b492ed3ad9a7c8R217-R219), [[4]](https://github.com/ImperialCollegeLondon/PyProBE/pull/153/files#diff-441aec132d927ef70cd9824112874874d1fb11d9d8bc0604c3b492ed3ad9a7c8R241-L162))
• Updated the process_cycler_file and process_generic_file methods to include the compression_priority parameter. ([[1]](https://github.com/ImperialCollegeLondon/PyProBE/pull/153/files#diff-441aec132d927ef70cd9824112874874d1fb11d9d8bc0604c3b492ed3ad9a7c8L64-R110), [[2]](https://github.com/ImperialCollegeLondon/PyProBE/pull/153/files#diff-441aec132d927ef70cd9824112874874d1fb11d9d8bc0604c3b492ed3ad9a7c8R217-R219))
• Add the functionality to skip re-generation of parquet files if they already exist

Code Refactoring:

• Extracted the file conversion logic into a new private method _convert_to_parquet to simplify the process_cycler_file and process_generic_file methods. ([[1]](https://github.com/ImperialCollegeLondon/PyProBE/pull/153/files#diff-441aec132d927ef70cd9824112874874d1fb11d9d8bc0604c3b492ed3ad9a7c8L64-R110), [[2]](https://github.com/ImperialCollegeLondon/PyProBE/pull/153/files#diff-441aec132d927ef70cd9824112874874d1fb11d9d8bc0604c3b492ed3ad9a7c8R217-R219))
• Modified the _write_parquet method to accept a compression parameter and use it when writing the parquet file. ([pyprobe/cell.pyR323-R335](https://github.com/ImperialCollegeLondon/PyProBE/pull/153/files#diff-441aec132d927ef70cd9824112874874d1fb11d9d8bc0604c3b492ed3ad9a7c8R323-R335))

Documentation and Examples:

• Added new code cells and markdown explanations to the comparing-pyprobe-performance.ipynb notebook to demonstrate the new compression options and their performance. ([[1]](https://github.com/ImperialCollegeLondon/PyProBE/pull/153/files#diff-f97df501eeb86d9944940d597c2c80a87b666e5ecd0715eb1cd37238964dc9e1R326-R334), [[2]](https://github.com/ImperialCollegeLondon/PyProBE/pull/153/files#diff-f97df501eeb86d9944940d597c2c80a87b666e5ecd0715eb1cd37238964dc9e1R357-R397))

Testing:

• Updated the test_process_cycler_file test case to include the compression_priority and overwrite_existing parameters. ([tests/test_cell.pyL76-R83](https://github.com/ImperialCollegeLondon/PyProBE/pull/153/files#diff-5f57142fa1c2be045e3012de7f735da962b090fe45c8957a3deef79bb4819677L76-R83))
