Goal is to move chronik.js out of utils and improve formatting and organization of its functions and unit tests
Start with parseChronikTx as there are some additional tests and bugs to patch here.
This diff preserves the existing test cases with the existing mocks. It renames them and organizes them into a vectors array instead of a long list in the test file.
parseChronikTx is moved from src/utils/chronik to src/chronik/index.js
