Get electrs source tarball with gpg verified sha256 and corresponding helper script 

move script to pkg dir, add hint to script in pkg def

remove unneeded script deps

add extended bash error checking

rename DIR -> TMPDIR

remove TMPDIR on exit

strip whitespace, simplify comments

gpg2 -> gpg

latesttagelectrs -> latest

tmpdir: don't use XDG_RUNTIME_DIR

XDG_RUNTIME_DIR is often in RAM and shouldn't be used for larger
workloads like repo downlaods

verify fingerprint of the imported key

remove trailing '-' in output

simplify output

Hide --fetch-key output

Output is not relevant to user, looks better without it

More accurately describe ./get-sha256 function

User might think that ./get-sha256 automatically updates sha256 in default.nix

Fetch key from sks keyservers instead of keybase.io

Using --recv-key simplifies getting the right key, and only the
right key, greatly. I try to refrain from using sks keyservers,
but the certificate spamming attack shouldn't be an issue in this
case because we create a temporary keychain just for the
verificaiton.

remove unneeded cargoDepsHook

Make clang nativeBuildInput instead of buildInput
