Use a in memory cache instead of file storage

[REQUIRED] Use case description

I often use caching of manifests and segments for content, now there is a single Cache implementation -> SimpleCache, which works with file storage, and there is a need to solve the following problems:

1. I want to write less to disk so as not to consume device resources;
2. On some TV devices, read/write operations take a long time;
3. Users have errors related to reading/writing to the file system (they cannot create a directory or file; there is not enough space on the device).

Therefore, there is a desire to try using temporary RAM instead of the file system for sometimes, and of couse it's will work only for an active sessions. Also, this type of cache will most likely need to be used with lower maximum MB storage values.

Proposed solution

Maybe, create a implementation of the androidx.media3.datasource.cache.Cache interface that will work with RAM instead of the file system, named InMemoryCache for example.
