Add support for later node versions

[ngaruko]

At the moment, apparently medic-couch2pg does not work with node versions greater that 10.
With the v14.16.0 , I couldn't get the node . command to do anything. No error in the logs just the first json.

More on this was added in the README notes:

Error installing deps ERR! ... node-pre-gyp install --fallback-to-build

When installing Node.js dependencies locally or building the docker image, you might get an error like:

...
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] install: `node-pre-gyp install --fallback-to-build`

It is probably related to a gcc library that is failing with some versions of Node and npm, try with Node 10 without updating the npm version that comes with it.

2 more things that are very related to this:

1. Dependencies are very outdated, with 45 vulnerabilities, 2 of them critical:

   $ npm ci
   
   added 953 packages, and audited 954 packages in 25s
   
   -45 vulnerabilities (26 low, 2 moderate, 15 high, 2 critical)

   The library node-libcurl that cause the error in some versions of node / platforms is one the outdated libraries so upgrading it for sure will solve the problem.

2. We released a new version of couch2pg around a month ago: v.0.6.0, this project relies on it but we are using instead the v0.5.0.

@garethbowen can we prioritize this so next release not only is a rebranding from mediccht-couch2pg but we also fix this that my guess is that will only require to execute npm audit and upgrade the version of couch2pg?

I think couch2pg 0.5 and 0.6 are identical due to a glitch during publishing, so I don't think bumping that version will do anything. In general we should aim to bump dependencies every release at least for non-breaking changes, so it'd be good to do this, potentially for both libraries at the same time.
