httpRequestorFromAxios(instance, options): HttpRequestor

An SDK HttpRequestor over an axios instance, so the SDK's requests travel through the app's own base URL, interceptors and error handling.

A POST's string body is parsed back to the object the SDK serialized it from (axios serializes again, and an interceptor may read the object); a GET goes through instance.get. The answer is an HTTP response whose json()/text() read response.data. An answer that is not an axios response is a TRANSPORT_ERROR rejection, and so is a rejection that means no HTTP answer arrived (the original error is cause): any rejection with rejectOnHttpError: false (every status resolves there), an axios error without a response with true. Any other rejection (an interceptor's error for a 4xx, say) is rethrown unchanged, and so is an abort.

Pair it with ChainGateway's dexBackendBaseUrl: '' when the instance owns the base URL.
