Add optional progress bar display during PSF and datacube calculations

[mperrin]

Minor. Adds a progressbar bool parameter for displaying a progress bar for status during long PSF or datacube calculations using the optical system calc_psf or instrument class calc_datacube functions.

Requires optional dependency tqdm, which I have intentionally not made a required dependency as part of this PR, since this is an optional feature for a cosmetic display during calculations, not otherwise used anywhere within poppy.

@obi-wan76 @BradleySappington Good morning, I realized I never tagged anyone to review this PR from some months ago. This adds a minor 'quality of life' improvement to optionally display progress bars during long calculations. Hopefully straightforward for one of you to review, thanks.

I haven't used tqdm before, what an elegant solution! Nice work

[mperrin]

@BradleySappington yeah tqdm is quite nice. It makes it super easy to add a progress bar to any for loop or other iteration. The actual progress bar display part of this PR is tiny and succinct compared to the extra contortions I put in to make it optional and configurable with a function parameter. 😆

@mperrin Lol, such is the way, "Yes, this works so easy!....now work for me..."
