This PR removes the PolyDatabase type to simplify the library usage.
[x] One can always open a Database with newly introduced Unknown types which don't implement the BytesEncode/Decode traits, forcing the user to Database::remap_types.
[x] I made the Database::is_empty method use the Database::length instead of allocating a cursor to see if there is at least one element.
[x] I also introduced a new DatabaseOpenOptions struct to create or open a database akin to the EnvOpenOptions struct.
[x] I need to document the DatabaseOpenOptions struct.
[x] I moved the LazyDecode and Lazy types in the heed-types crate.
