‌‌Provide support for the Mastodon filter v1 API for gotosocial

**Describe the bug**
In the instance of Gotosocial, the Mastodon filter v1 API is used to achieve filtering functionality.https://github.com/superseriousbusiness/gotosocial/pull/2594

Opening the filter page of Phanpy will only display "Unable to load filters." The action of creating a filter is also not supported.

I thought this was an issue with masto.js and submitted an issue to them. Here is their reply: https://github.com/neet/masto.js/issues/1059
