[tillh-stripe]

Summary

This pull request adds an ElementsContext struct to the Instant Debits flow, allowing us to pass in information from the hosting surface.

Right now, this is only used with the LinkMode in Instant Debits flow, but can be extended to more properties and to the ACH flow.

Love this approach! it scales (both for adding more context to elements, or following the same approach for new contexts if needed). Just a minor comment.

[carlosmuvi-stripe]

same as above : )

[tillh-stripe]

This one is a little trickier, since CollectBankAccountConfiguration.USBankAccount is public. Good if we revisit this later this year for the next major version bump?

[carlosmuvi-stripe]

sounds good! When we do that ideally we also move it out of the configuration object (that intends to be public facing) and follow the Args pattern we do on FC 😄
