Event handling in get_logs return type. Includes version bump to v0.0.39

[slundqui]

Solves #48

This PR adds typed dataclasses as the output of get_logs, with well defined types on the output.

Important changes:

• This PR introduces pypechain itself as a dependency on any generated classes in an effort to reducing the amount of code generated.
• We introduce a new function get_typed_logs that returns a dataclass. Web3's get_logs remains unchanged.

I think the gains are worth adding an additional opinionated flow. Great work!
