fix(types): make types retrocompatible to typescript 4.5.5 (#571)
* fix(types): spread and embeding combination issues * chore: remove debug test case * chore: reproduce invalid node type error * chore: using type fix the test * fix(types): types result with schema as any * wip: make parser logic retrocompatible * wip: almost there * chore(types): make GetResult compatible with typescript 4.5.5 * chore: fix merge * chore: finish merge * chore: revert non essential changes * chore: add TODO --------- Co-authored-by: Bobbie Soedirgo <bobbie@soedirgo.dev> Co-authored-by: Bobbie Soedirgo <31685197+soedirgo@users.noreply.github.com>
