Rewrote the "JoinMarket Maker Clustering and Taker Anonymity-Set Reduction" article with a clear example as introduction, a glossary, and trimming most sections.

Published at https://joinmarket-ng.github.io/coinjoin-simulator/mainnet-deanon.html (same URL, old version preserved in git).

The discussion about possible mitigations is ongoing at https://github.com/joinmarket-ng/joinmarket-ng/issues/508

BTW the JM protocol is not broken, just improvable.
