shahddaghash cfbd6c5493 Add ability to force Transformer failure in Robolectric tests
When `forceTransformerToFail` is set to true, the builder will use a `FailingMuxerFactory` which creates a `FailingMuxer` that throws a `MuxerException` when attempting to write sample data. This ensures Transformer will fail as muxers are used for all cases (transmuxing and transcoding).

Transformer module

Provides functionality for transforming media files.

Getting the module

The easiest way to get the module is to add it as a gradle dependency:

implementation 'androidx.media3:media3-transformer:1.X.X'

where 1.X.X is the version, which must match the version of the other media modules being used.

Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.
