Describe the feature you would like

There was an implementation under mpt-witness-generator/trie/stacktrie.go already, but still has some bugs. This issue is mainly to fix it.
See Miha's doc for more details.

This is partially resolved by #1779, but would be good to add some further tests which would test GetProof more extensively, especially for the hashed trie (like TestGetProof). Also, it would be nice to have some tests that check whether the number of proof elements (for elements with a bigger depth) is as expected and the leaf (the last proof element) is as expected...

Feat/#1752 fix witness generation - adding testing (#1784)
b82ea41 
### Description

closed #1752 

- Adding different numbers of txs to test different trie status (e.g.
one leaf only, one ext. , one branch and one leaf ...etc)
- Fixing `GetProof` (if input is an ext node, it always assign first
child of the root ext. node, `st.children[0]`)
- Fixing `getNodeFromBranchRLP` (if input is an leaf, it could throw an
exception)
- Refactoring `getNodeFromBranchRLP`
