Allow filtering injection types

[hatemhosny]

This PR allows filtering injection types or disabling the extension in specific web pages using a meta tag, as discussed in #29 and #31

<meta name="codeium:type" content="monaco" />

The content attribute accepts a comma-separated list of supported editors. These currently include: "monaco" and "codemirror5".

To disable the extension in a specific page add the following meta tag:

<meta name="codeium:type" content="none" />

closes #31

hi @pqn This is a gentle reminder. It seems that this version has not yet been published to chrome store, so that my users can use this feature. Thank you.

It should be released now.
