Library should not panic

[parsnips]

The library uses panic in cases where it can return an error. Suggest in cases where multiple errors be returned to return the first error.

SynapseGo/request.go

Lines 56 to 58 in 9d3ed7f

	if len(errs) > 0 {
	panic(errs)
	}

SynapseGo/request.go

Lines 84 to 86 in 9d3ed7f

	if len(errs) > 0 {
	panic(errs)
	}

SynapseGo/request.go

Lines 112 to 114 in 9d3ed7f

	if len(errs) > 0 {
	panic(errs)
	}

SynapseGo/request.go

Lines 133 to 135 in 9d3ed7f

	if len(errs) > 0 {
	panic(errs)
	}

In this case I'd return an error here... Even better suggestion is to make the Response just be a []byte so that clients can marshal into their own structs, and get rid of readStream entirely.

SynapseGo/read.go

Lines 11 to 14 in 7a3e060

	// if data is an empty stream this will cause an unmarshal error
	if err != nil {
	panic(err)
	}
