Use small HTTP dependency (#110)

Replace request with teeny-request. Improve startup time by 400 ms.

request is a large module because it has so many options and features. That
requires both extra bandwidth and space, and also extra time to load and
parse the module every time codecov is run.

Uploading the reports only uses a minimal subset of request's features.
request can easily be switched out with a much more lightweight dependency.
