This PR fixes a bug where you where not able to override top module from the CLI while using a flow file. For example like this:
f4pga -vv build -f basys3.json -Dsources=[Blinky.sv] -Vtop=Blinky
where basys3.json looks like this:
{ "default_part": "XC7A35TCPG236-1", "XC7A35TCPG236-1": { "default_target": "bitstream", "dependencies": { "build_dir": "build/basys3", "xdc": ["basys3.xdc"] } } }
This resulted in an error where tool would complain that no top module if no top module is defined in basys3.json. The value from the top option was never passed to the flow configuration.

I appreciate how you simplified the code for global dependency overrides, but you dropped an entire part for overriding dependencies defined per-stage.

Oops, thanks for letting me know. I was probably a little too quick to open this pull request. I will try to fix this when I have time.
