If it breaks the json in half it's a them problem but if not it can be
useful for the user to see when getting a debugging configuration to
work.

The C/C++ ones are well behaved, attached install and dape-configs for
you to able to pick and choose. They are quite quiet though so for
checking performance vscode-js-debug and debugpy are better
options. But start with the C/C++ ones.

Included attachment with install fns and configs for the C/C++
adapters.

Super! But maybe that can wait, jsonrpc seams to me like a higher
priority thing.

For the changes in dape.el to accommodate jsonrpc, I think it would be
beneficial to collaborate on a some type of feature branch.
