[FEAT] View per-column metadata about parquetviewer HOT 3 CLOSED

Thank you for the feedback. I reverted the extra info I added to the thrift metadata being shown. And added a "Copy Raw Metadata" button as you suggested. You can find this new feature available in: v2.7.2.1

Really appreciate the ideas to help make the app better. Closing out this ticket for now but feel free to reopen if required.

I added some column metadata to the row groups in https://github.com/mukunku/ParquetViewer/releases/tag/v2.7.2 . Can you check it out and see if that's good enough for your needs?

@mukunku I see the column metadata (KeyValueMetadata) in each row group. I like that the byte sizes of each column are now available to get an idea of how well each column is de-duplicating and compressing.

This extra information also greatly increases the line count of the metadata window (2,440 -> 78,498), so I copied the json into Visual Studio Code to make use of the collapsing and search. I may have too many row groups... Anyways doing more with the UI will have diminishing returns because other editors will do a better job. Maybe a copy button would be the extent of any change I would suggest to the metadata viewer window?

Thank you for your tool and I'm now able to use this feature request for what I needed.
