In particular, according to ZIP 234 the deployment occurs only once the NSM subsidy would drop below the legacy subsidy, and so the four-year periods used for comparison no longer line up with halving periods. Occurrences of ZSF have been changed to NSM.

This also updates INITIAL_SUPPLY to take into account unclaimed mining rewards up to the second halving, according to zcash-cli getblock 2726399 | jq '.chainSupply'. After the second halving, which coincides with NU6 and activation of ZIP 236, there can be no further unclaimed mining rewards.

The README has been updated with the new output, and a disclaimer added. The vertical scale of the graphs has also been adjusted so that the curve uses more of the space.

Dependencies have been updated, primarily to update to a version of the font-kit crate that fixes a memory safety bug.

This fork of Eiger's "[ZSF simulator](https://github.com/eigerco/zsf-simulator)" has been
significantly modified by me, Daira-Emma Hopwood. Any errors in the interpretation of
ZIP 234 are my own.

This wording makes sense in your fork, but it will read a bit oddly once we merge it back into the upstream repo.
Could you instead add the “Contributors” section now, and keep that note for the point when you add it? Then after the merge it’ll still read naturally.
