no-std support for monero-serai (#311)
* Move monero-serai from std to std-shims, where possible * no-std fixes * Make the HttpRpc its own feature, thiserror only on std * Drop monero-rs's epee for a homegrown one We only need it for a single function. While I tried jeffro's, it didn't work out of the box, had three unimplemented!s, and is no where near viable for no_std. Fixes #182, though should be further tested. * no-std monero-serai * Allow base58-monero via git * cargo fmt
