File extension .eot not supported

[th0rgall]

Description and Context

I got a weird problem in my HS project: .eot font files didn't get uploaded to my theme, throwing this error:

[ERROR] The file "sr-theme-customized/fonts/suisse-intl/SuisseIntl-Black-WebS.eot" does not have a valid extension

Steps to reproduce

Upload a file with the .eot extension using hs upload.

What I tried

I made a fork and tried to add eot to the ALLOWED_EXTENSIONS list, see here https://github.com/th0rgall/hubspot-cms-tools/pull/1/files#diff-c360fc5df10a4024db0e2534d8de43092761d7a1e2805bac489a5a76e25fdc19R20

I assume this "passes" the eot file through the client-side CLI validations for files. But when I tested this change, I got a different error

[ERROR] Failed to process file /<omitted>/sr-theme-customized/fonts/suisse-intl/SuisseIntl-Black-WebS.eot. File extension 'eot' is not supported

Since I didn't see any other references to allow lists in the CLI client code, I assume this is a HubSpot server validation error, which I'm not able to fix.

Expected behavior

Allow fonts with the .eot extension to be uploaded.

@th0rgall I'm looking into adding support for these files. I'll check back here when I have an update.
