Description Devin Rousso 2022-07-27 14:58:48 PDT

we currently offer the `version` as an indirect way for developers to answer the question "does the current device support this feature" since the developer can look up the version that supports that feature <https://developer.apple.com/documentation/apple_pay_on_the_web/apple_pay_on_the_web_version_history>

while there's nothing wrong with this, it's a pretty inflexible (monotonically increasing integer) and not directly clear approach (requires looking at documentation to know what something means)

we can instead have a list of `features` that contains an `enum`, allowing developers to call out desired features by name, allowing for more more options and avoiding having to look at documentation
