SignatureMethod and DigestMethod

[lostvicking]

Thanks for very useful library! I am using it as an SP and have a Signature Validation issue where the destination IDP is not able to verify the signature I generate because they use

<ds:SignatureMethod Algorithm="http://www.w3.org/2001/04/xmldsig-more#rsa-sha256"/>
<ds:DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1"/>

From what I understand in samlify the DigestMethod is picked based on what is set for the SignatureMethod -- I can see that when constructSAMLSignature is called in libsaml.ts the digest method is determined by getDigestMethod(signatureAlgorithm). I would like to be able to configure the library to use "rsa-sha256" for the SignatureMethod and "sha1" for the DigestMethod -- is this possible?
