tools: Add src/container
Contains generic Map and Set types.
Golang 1.18 added new support for generics, but has not yet added a standard library that provides generic containers. In future versions of Golang, there will almost certainly be similar implementations of these types.
Until then, use these to simplify some code.
100% test coverage.
