Template strings are not interpolated in mapping.ts

Bug.

What is the current behavior?
Template strings are not interpolated in mapping.ts.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.
I encountered this while reconstructing an IPFS CID from a 32 byte sha256 digest value.

// This doesn't evaluate hashDigest.toHexString().slice(2).
// Instead it just returns the raw string.
const hexStringConcatenated = `1220${hashDigest.toHexString().slice(2)}`

// Workaround.
const hexStringConcatenated = `1220` + hashDigest.toHexString().slice(2)

log.info("New market with CID {}", [cid])

What is the expected behavior?
ES6 Template Strings are interpolated correctly.

Mappings are not written in ES6 but in AssemblyScript, which still doesn't seems to support template strings.

This is the relevant issue on their repository:
