Updates for web3py v7.6. Includes version bump to v0.0.48 (#151)

This PR updates pypechain to work with web3py v7.6. Solves both
#149 and
#150. Includes version bump
to v0.0.48.

## Breaking Changes
- `my_contract.events.MyEvent` is no longer a type, but instead the
instantiated object. This means calls to e.g.,
`events.MyEvent().process_receipt_typed()` will now be
`events.MyEvent.process_receipt_typed()`.

## Major changes
- Changing handling of `my_contract.events`. Note overloaded events
still are not implemented.
- Adding new pypechain class `PypechainOverloadedFunctions` that acts as
a wrapper to the underlying overloaded functions.
- Delay calling the overloaded function factory until the arguments gets
bound to the contract function.

## Minor changes
- Pin web3py to v7.6 for futureproofing.
- Separate makefile builds to test and example.
- Using solidity compiler 0.8.24 for test gen.
