anchor-contrib: AnchorTypes doesn't parse methods correctly

[0xksure]

The AnchorTypes method

saber-common/packages/anchor-contrib/src/types.ts

Line 218 in d344ded

export type AnchorTypes<

works as expected for instructions. However, for methods it looks for a method field which is not present in the idl. Could consider using anchors way of generating the methods type from the idl.

Do you know if this issue is present in @project-serum/anchor? If not, maybe we should deprecate anchor-contrib.
