Incorrect coder matching from namespaced library

[petertonysmith94]

Summary

Consider the library, with the generated ABI type of enum data_structures::order_change::OrderChangeType:

// Namespaced to "data_structures.order_change"
library;

pub enum OrderChangeType {
    OrderOpened: (),
    OrderCancelled: (),
    OrderMatched: (),
}

Incoming from the forum.

Actual

Currently, this type will match to a StructCoder due to the struct in the namespace.

Expected

Should match to an EnumCoder.

Solution

Our RegEx on ABI types should match to the start of the string.
