Specify signing method and digest method algorithm

[Weasy666]

Hello!
If taken a look at the code, but couldn't find a way to specify the algorithms used for signing method and digest method. It seems like it is hardcoded to:

• signing method: http://www.w3.org/2001/04/xmldsig-more#rsa-sha256
• digest method: http://www.w3.org/2000/09/xmldsig#sha1

for a special german SAML IdP i would need:

• signing method: http://www.w3.org/2007/05/xmldsig-more#sha256-rsa-MGF1
• digest method: http://www.w3.org/2001/04/xmlenc#sha256

The IdP does not accept any other algorithm.

Would it be as easy as just replacing the hardcoded strings, or would i need to change something within the crypto module?

crypto module would need to be updated to support those methods, for example: https://github.com/njaremko/samael/blob/master/src/crypto.rs#L682

I think signature module would also need to be changed, here https://github.com/njaremko/samael/blob/master/src/signature.rs#L31-L33 and here https://github.com/njaremko/samael/blob/master/src/signature.rs#L49-L51.

Sorry, life's been hectic, getting back to this, the stuff you're referencing is just templates, you can manually set all those fields on those structs dynamically, have you tried that?
