Update mesh-sdk-go
What's changed
A newer release of mesh-sdk-go provides more features, in particular some improvements to outgoing headers.
This release removes some of the geth-specific handling of outgoing headers using the context.
Context
In order to keep header management simpler, this PR removes some of the context management to make go-ethereum
add headers to requests. Instead, the HeaderForwarder http.RoundTripper
will do the work of managing outgoing headers to native nodes as well as incoming headers.
