I'm looking for a solution for the wasm-testing job, please don't merge this in the meantime

[zoedberg]

I've opened BP-WG/bp-esplora-client#8 and add a commit here to fix the wasm build (I'll change the git dependency after the PR gets merged or I'll remove it if you release a new version of bp-esplora-client). Unfortunately there's no way to conditionally exclude dependencies based on target, so I had to add a dedicated feature for wasm. Moreover wasm-pack doesn't seem to provide a way to select features (it uses the default ones), so I had to remove all default features from here. CI is still failing because of some missing feature gates (unnoticed because of the default features), I will fix this tomorrow or in the following days

There is:

[target.'cfg(target_arch = "wasm32")'.dependencies]
# your dependencies

[zoedberg]

Sorry, I meant features, not dependencies. I've found this related open issue rust-lang/cargo#1197 so it seems it's not possible at the moment

@dr-orlovsky all CI jobs pass, IMO this can be merged
