Add a simple whitelist to config

[wolffshots]

This pull request primarily introduces a new feature to the stream_server component, which adds support for an IP address whitelist. This enhancement allows users to specify which IP addresses are permitted to connect to the stream server, providing an additional layer of security.

Let me know if you would like this to be included and I can update the docs to be a bit more unified. All good if you'd rather close the PR though.

Key changes include:

Documentation Updates:

• Updated README.md to reflect the new whitelist feature and provide configuration examples. [1] [2]

Feature Implementation:

• Added a new configuration option CONF_WHITELIST to the stream_server component in components/stream_server/__init__.py. [1] [2]
• Modified the to_code function to handle the new whitelist configuration.

Code Enhancements:

• Implemented the whitelist logic in components/stream_server/stream_server.cpp:
  • Added methods to check if an IP is whitelisted and to log the whitelist. [1] [2]
  • Updated the accept, flush, and write methods to enforce the whitelist. [1] [2] [3]

Header File Updates:

• Updated components/stream_server/stream_server.h to declare the new whitelist-related methods and member variables. [1] [2]
