Describe the feature

The idea is pretty simple: allow other developers extend existing encoding mode, so that they appear in native AE terminals. This eliminates the need for other developers to create in-house encoders, and also collect all encoders in one place - native terminal.

Reasons why it should be considered

Currently, PE modes are hard-coded as an enum (see EncodingMode).
Therefore, other developers are creating their own encoders, like FramedBlocks does (see FramingSawWithEncoderScreen).
