f9d2a23132 fix(lotus-sim): correctly handle cancellation in walk 
1. Select order is not guaranteed, always check if the context has been
canceled explicitly.
2. Never close a work channel unless we're actually done. This can yield
out-of-order results due to buffering.

52261fb814 refactor(lotus-sim): enterprise grade 
While the previous version "worked", this version nicely separates out
the state for the separate stages. Hopefully, we'll be able to use this
to build different pipelines with different configs.

2b4f865665 feat(lotus-sim): fund from a funding account 
Instead of funding the simulation from the burnt-funds actor, fund from
a custom account and take a "tax" to fund that account.

Otherwise, we run out of funds...

86e459f585 feat(lotus-sim): return receipt 
Instead of returning a "full" boolean and an error, return a receipt and
an error. We now use the error to indicate if the block is "full".

c5dc67ccd8 feat(lotus-sim): add a walk function 
This way, we can easily walk the chain and:

1. Inspect messages and their results.
2. Inspect tipset state.
