this is the powah of maca and cacao

today, i was so charged up that i powered through 2 hours of making it so i can generate taproot addresses from private keys without importing btcd.

then i noticed that i could have omitted the taproot address generation function and the btcd dependency would have vanished.

i chased that thing like a hungry dog after a bone, gnawed it until it was all swallowed and then sat there grinning like a staffordshire terrier.

haha.

in the process i now have some essentials that never need btcd again:

chain configuration for mainnet, including all the official checkpoints, genesis block and its coinbase.

there is a couple of odd things in the mix that may need updating some day, but probably not, so this is one little step towards btcd elimination.
