ECDH library isn't a library.

[TomAFrench]

zk-kit.noir/packages/ecdh/Nargo.toml

Line 3 in e7f493f

type = "bin"

The ECDH library is currently marked as a binary crate and so it cannot be imported as a dependency from another crate.

I tried running nargo check and nargo compile (in ecdh/ directory) without making this change. Both failed with the following error:

error: Non-comptime variable `x` referenced in comptime code
    ┌─ /home/user/nargo/github.com/noir-lang/ec/v0.1.2/src/tecurve.nr:104:22
    │
104 │             self.a * x * x + y * y == 1 + self.d * x * x * y * y
    │                      - Non-comptime variables can't be used in comptime code
    │

after changing the type to "lib" the error is gone for ONLY nargo compile. The error persists for nargo check.

This is as nargo compile skips any library crates as there isn't an entrypoint function to compile into a circuit.
