Use bdk_electrum upstream

[reez]

Describe the bug

Just adding an Issue to track that we will move back to bdk_electrum (and not a fork of it) at some point.

Changed in bdk-ffi alpha 13:

bdk_electrum = { git = "https://github.com/thunderbiscuit/bdk/", package = "bdk_electrum", branch = "feature/electrum-client-ring-ffi-alpha13", default-features = false, features = ["use-rustls-ring"] }
# bdk_electrum = { version = "0.15.0" }
