form file inputs should be able to accept mime types other than json

[davetsay]

I need form file inputs to be able to accept images, and to pass the file on instead of reading in the file.

for VIPER

Testing Instructions

• verify from the VIPER issue in which this is used.

Verifed Fixed - Testathon 1/17/23

Vector... no issues. Was able to verify by name it was uploaded

Raster is HUGE, took forever, first one failed because of the name being the same as one that was already uploaded, didn't really see the error, but I did see it in the errors notifications. I think there should be some feedback on how the upload is going...

Otherwise it worked without issue, was able to verify raster was uploaded.

Keeping this open until we can validate the Map Layer upload behavior
