- Don't touch <fmt/std.h> because it touches std::filesystem which makes
macOS throw a hissy fit and refuse to compile.
- int_to_string is broken on macOS because it uses std::to_chars which
makes macos throw a hissy fit like a cranky old female cat seeing a
kitten if it sees it.
- wallet3 was using std::filesystem and std::visit, both of which make
macos throw a hissy fit. (There is a pattern here). Apply the dumb
fs::path and var::visit workarounds needed to appease this garbage OS.
- use var::get (from oxenc/variant.h) instead of std::get because, oh
yeah, we need to support a garbage OS that Apple themselves don't even
properly support. Yay!
demo is vaguely presentable now. syncing and basic tx send work.
change output was being sent to void (change address was unimplemented)
but that works now as well.
Fixes a few merge conflicts, several compilation errors, and
some behavioral incorrectness. Still a few bugs with wallet3
but as far as I can tell wallet2 and daemon etc. should be working
correctly.
