# Description of Changes
Introduces types `TypedIndexKey` and `IndexKey` to free the table index
code on its direct dependency on `AlgebraicValue`, allowing index scans
by BSATN, `RowRef`s as well without first going through
`AlgebraicValue`.
This also has the effect of optimizing string scans by avoiding
allocating in `AlgebraicValue::String`.
This also adds a byte-array based future optimization for
all-primitive-multi-column indexes.
Also in the future, this will enable optimizing `iter_by_col_eq`, which
is used by the frequent connect/disconnect logic.
# API and ABI breaking changes
None
# Expected complexity level and risk
3? Unsafe code and very load bearing code.
# Testing
Should be covered by existing tests.
