5.0.1 - Bugfixes

• Made some fixes to Vault.get to use the @overload decorator so IDEs doesn't get confused with what implementations are available.
• Made a fix for when using validators and modifiers together when adding values to the vault using insert. In this case, it would validate without modifying the value. It would also validate the value twice, which shouldn't be necessary. It does mean that MiniVault.build doesn't validate the keys, but that's fine because you still cannot write a faulty value for key to the vault.
