This commit moves the previous implementation of `SparseMerkleTree` from
miden-core to this crate.
It also include a couple of new tests, a bench suite, and a couple of
minor fixes. The original API was preserved to maintain compatibility
with `AdviceTape`.

This commit introduces a workspace structure with a `Cargo.toml`.
Currently we have a single member `crypto`, but these can be added
incrementally in the future.
