The `Symbol_code` type being exported here is invalid

[aaroncox]

npx @wharfkit/cli generate -u https://telos.api.animus.is payroll.boid -f payroll.boid.ts

This results in:

    @Struct.type('tokenwl.rm')
    export class tokenwlrm extends Struct {
        @Struct.field(Symbol_code)
        sym!: Symbol_code
    }

Which is invalid. The Symbol_code field here is never defined.
