Exclude directories from the Composer archive

Proposed Changes

This results in a lighter package when it is installed in vendor in consuming projects. This makes a difference on AWS Lambda where the package size is limited, and a smaller package implies better performances for cold starts.

Thanks @mnapoli, this is handy. I didn't know that it also affects the composer releases.

Only one thing though: Can you remove the bin/ directory from .gitattributes, because bin/fcgiget gets linked on composer install, so this would be a BC break, see: https://github.com/hollodotme/fast-cgi-client/blob/v3.1.1/composer.json#L20

[hollodotme]

As discussed with @mnapoli via DM:

• I'll merge this PR which will exclude the bin/ directory from releases installed by composer
• I'll remove the link of bin/fcgiget in composer.json and document it as a security fix (because bin/fcgiget accepts any accessible fastCGI endpoint)
• I'll release it as v3.1.2

Approved, see conversation
