Added configurable timeout for API requests

This release adds support for setting a custom timeout on API requests, which helps avoid unexpected timeouts (see #3).

What's Changed:

• Added timeout option to Crawlbase::API initializer.
• The timeout sets both open and read timeouts for Net::HTTP.
• Default timeout is 90 seconds, based on Crawlbase’s recommendation.
• Added tests to make sure the timeout works as expected.

Let us know if you run into anything.
