CLI fixes and updates

[rosteen]

This enables loading multiple files with format specified through CLI. The user needs to be able to specify the file format for the loader to load files in deconfigged from the CLI. This enables that with a file_format argument, which should be specified for each file, e.g.:

jdaviz --layout=flexible -fp /Users/rosteen/Data/NIRCam/jw02727-o002_t062_nircam_clear-f277w_i2d.fits -ff Image -fp /Users/rosteen/Data/NIRCam/jw02727-o002_t062_nircam_clear-f150w_i2d.fits -ff Image

This PR also fixes the faulty rendering of extra file-browser and file-drop elements above the app when specifying a --layout argument from the command line.

Right now it feels inelegant to have to provide the (keyword argument) file formats all before the (positional argument) filenames, e.g.:

jdaviz --layout=flexible --file_formats=Image --file_formats=Image /Users/rosteen/Data/NIRCam/jw02727-o002_t062_nircam_clear-f277w_i2d.fits /Users/rosteen/Data/NIRCam/jw02727-o002_t062_nircam_clear-f150w_i2d.fits

It might make more sense to change filenames to a keyword argument as well so you could provide each filename/format pair in a sensible order. Thoughts?

is there some auto-generated place we can point to for this (perhaps index on the formats page) so we don't risk this getting out-of-date?

[rosteen]

I can try to do that. There's definitely an error message that pops up in the UI if a compatible format isn't found listing them all, I'll find where that comes from.

[rosteen]

Hm, the list in the formats index page is hard coded as well, not auto generated. I'll link there so at least we only have to update one place.

[rosteen]

Updated.
