The code compile Error from_bits not found

[NoorahSmith]

no function or associated item named from_bits found for struct Scalar in the current scope

This is due to Scalar::from_bits being deprecated in curve25519-dalek v4.0.0-rc.3.

The following patch will make it compile:

diff --git a/Cargo.toml b/Cargo.toml

although it'd be better to remove the use of Scalar::from_bits if possible.

okay. it compiled with the patch . but in order to remove Scaler from bits altogether , will need to implement something like compressedpoint. uncompress public key
