🕓 Changelog

This PR refactors the BatchDistributor contract to make it module-friendly and ready for the breaking 0.4.0 release. Please note that the @nonreentrant decorator also works on internal functions and we have added this decorator to the internal function _distribute_token to prevent potential cross-function reentrancy via _distribute_ether. The underlying reason for adding the @nonreentrant decorator to internal library functions is an additional protection when people import the module and use the internal functions of the module without being aware of the potential danger of reentrancy and therefore forget to add the @nonreentrant decorator to the external functions.

NOTE TO MYSELF: Ensure nonreentrant decorators work properly on internal functions. DONE (test added via d036d7e).

### 🕓 Changelog

We bump the Vyper version to the latest breaking release `0.4.0`
(technically, since Vyper `0.4.0` has not been released yet, we use the
latest release candidate
`0.4.0rc6` (https://github.com/vyperlang/vyper/releases/tag/v0.4.0rc6)
instead), which implements _stateless_ (see
vyperlang/vyper@c6f457a)
and _stateful_ modules (see
vyperlang/vyper@8ccacb3).
Furthermore, all existing `🐍 snekmate` contracts have been refactored to
be module-friendly (closes #221):

- [x] Authentication
  - [x] `ownable` (#218)
  - [x] `ownable_2step` (#219)
  - [x] `access_control` (#216)
- [x] Extensions
  - [x] `erc2981` (#233)
  - [x] `erc4626` (#236)
- [x] Governance
  - [x] `timelock_controller` (#220)
- [x] Tokens
  - [x] `erc20` (#234)
  - [x] `erc721` (#237)
  - [x] `erc1155` (#238)
- [x] Utility Functions
  - [x] `base64` (#222)
  - [x] `batch_distributor` (#223)
  - [x] `create_address` (#224)
  - [x] `create2_address` (#225)
  - [x] `ecdsa` (#227)
  - [x] `message_hash_utils` (#227)
  - [x] `signature_checker` (#228)
  - [x] `eip712_domain_separator` (#229)
  - [x] `math` (#230)
  - [x] `merkle_proof_verification` (#231)
  - [x] `multicall` (#232)

Furthermore, this PR closes the following issues:
- [x] Closes #175 (#243),
- [x] Closes #184 (#239),
- [x] Closes #180 (#240).

Eventually, the following changes are implemented:
- [x] Use `snake_case` notation for module and mock contracts. (#242)
- [x] The mathematical utility functions `_log_2`, `_log_10`, and
`_log_256` are renamed to `_log2`, `_log10`, and `_log256`. (#242)
- [x] Add documentation on how to use 🐍 snekmate contracts as modules.
(#247)
