- Flush and close console/file output streams manually on process exit
- Simplify the `BrokenPipeError` fix, as streams are already flushed

- Add `StreamWrapper` base class which passes through everything
  to the given `TextIOWrapper` object. Don't subclass from
  `TextIOWrapper` or `TextIO`.
- Wrap and replace `sys.stdout` / `sys.stderr`
- Restore on `ConsoleOutput.close()`
- Fix typing in `ConsoleOutput`

Move terminal-related functions to `streamlink_cli.console.terminal`

- Add `ConsoleOutput.msg_status()` method for writing status messages
  to the console output, if supported by the output stream
- Implement line-buffered `ConsoleOutputStream` which handles all
  writes to the console output and which doesn't support status messages
- Implement `ConsoleOutputStreamANSI` with support for status messages
  via ANSI control sequences
- Add feature detection to the `ConsoleOutputStream` constructor,
  so the right class is instantiated automatically

Next: Add support for the "classic Windows Console" APIs

Add support for "classic Windows Console" APIs that allow
the implementation of status messages without ANSI control sequences.

- Pass the `ConsoleOutput` instance to `Progress`, as well as
  the output file path, and pass an optional `Progress` instance
  to `StreamRunner` instead of instantiating it there
- Make `Progress` call the newly added `ConsoleOutput.msg_status()`
  method for each progress status update message instead of writing
  messages to `stderr` and adding whitespace padding to each line

NEXT:
If `--progress=force` is set, make `Progress` write non-status messages
to the console output in a slower interval

Restore the `--progress=force` functionality by making it write
non-status messages to the console output if the console output
doesn't support status messages (not a TTY stream). In this case,
increase the update interval from 0.25 seconds to 2 seconds, so the
regular console output doesn't get spammed by the download progress.
