shared the DSG draft

Finished the first draft of the 2022 Deep-Sky Gems spreadsheet file. James Edgar gave me an Excel file with content scraped from the original source (or PDF). 'Course it was rather raw...

Excel's text-to-columns choked on it so I had to write custom formulae to parse the content. Sheesh.

Put it into a pretty table, add a checkbox and space for quick notes.

Uploaded to our shared drive for the Observing Committee to have a look at.
