Update scale.go

[alexqrid]

I see you update scale.go library, but the version of substrate-api-rpc (v0.4.0) that subscan depends on uses scale.go of v1.0.51 which is pretty old release. Do I need to update scale.go before starting to use subscan indexer or it will work with an old version of `scale.go? @freehere107
