Missing ExtendedSymbol

[aaroncox]

We don't have types for this.

Unsure if we need it or if Symbol itself handles it? I'm outta my depth without some research.

I was missing this type the other day. It is similar to ExtendedAsset which is provided by this library, so it would make sense if ExtendedSymbol is also there.

It's simple enough to get around this with a Struct, so nothing important. This is what I do now:

@Struct.type('extended_symbol')
class ExtendedSymbol extends Struct {
    static abiName = 'extended_symbol'
    static abiFields = [{name: 'sym', type: 'symbol'},{name: 'contract', type: 'name'}]
    constructor(sym: Asset.SymbolType, contract: NameType) {
        super({'sym': sym, 'contract': contract});
    }
}

const efx = new ExtendedSymbol('4,EFX', 'effecttokens')
