Description

Currently, the only way to compare errors in .gno packages is to use the equals operator ==, as users are limited to the standard errors package.

Gno should support other useful methods from the Go standard errors library, like errors.Is and errors.As, because it makes it easy to do error comparisons and brings it closer to idiomatic Go.

Btw, you don't need to wait for #239 to be done to just port those missing helpers.
Feel free to open a PR.
