Support for JSON-based post requests #34
Description
Is your feature request related to a problem? Please describe.
Posts are sent as FormData, which is backwards compatible, but harder to debug because of escape sequences.
Describe the solution you'd like
Mastodon API support JSON-based post requests since 2020 (at least), so we should reduce the code and make use of it.
Describe alternatives you've considered
Continue with complicated debugging and special processing for form data is not really an alternative in the long run.
