Update flow version to latest

[Brianzchen]

Update flow from 0.107.0 to 0.146.0 to establish a good base to continue further development on the project.

Also disable linting rules in particular areas so that yarn eslint . doesn't throw errors and we have a cleaner project

The major goal here is to clean up all flow errors without changing the underlying logic as I cannot be sure what the overall impact would be and also there are minimal tests in general

Closes #410

Ran compiler and tested on local vscode

thanks for this! I had to push through an update to 0.183.0 in 8e38e1e, but this PR has a lot of better fixes so I'd like to leave this open and rebase it when I get some time.
