45MB of dev-only files (ext/h3/src/tests, ext/h3/src/website) inside the gem

[oleksii-leonov]

Installed gem size is ~59MB, which seems too large.

I start looking inside the installed gem folder:

h3-3.7.4# du -sh * | sort -h

Inside the ext/h3/src/ folder:

It appears that a significant amount of space is consumed by ext/h3/src/tests (41 MB) and ext/h3/src/website (3.5 MB), which are not necessary for the published gem. Additionally, there are numerous other files (examples, etc.) that could be safely removed.

It is good practice to remove any files that are not necessary for the gem production functionality, to keep the gem smaller.

I am not deeply aware of h3 internals, but I believe the following folders could be excluded in gemspec safely to save ~45MB of size (reduce total gem size from 59MB to 14MB):

spec
ext/h3/src/examples
ext/h3/src/dev-docs
ext/h3/src/docs
ext/h3/src/website
ext/h3/src/tests

Good spot @oleksii-leonov

I'm not actively maintaining H3 any more but if you'd like to raise a PR to address this I'd be happy to review
