Issue and Steps to Reproduce

@guillaume-chervet As per my server gateway, they need ath value divide by 2 in dpop jwt payload.
if possible, can we have a extra param something like makeAthHalfInJWT divide by 2 (half) in configuration itself like below.
From this code...

       const configuration = this.configuration;
        const claimsExtras = {ath: await base64urlOfHashOfASCIIEncodingAsync(accessToken),};

to...

        const configuration = this.configuration;
        const athValue= await base64urlOfHashOfASCIIEncodingAsync(accessToken);
        const claimsExtras = {ath: configuration?.makeAthHalfInJWT ?  athValue.slice(0, athValue.length / 2) : athValue ,};

If you want me to send custom ath value like below, i can send it as extra param to generateDemonstrationOfProofOfPossessionAsync method.

await oidc.generateDemonstrationOfProofOfPossessionAsync( accessToken, urlSplit[0], method, ath );

Thanks in Advance.
