Add grasshopper functionality to js compute client

Evaluate grasshopper definitions with RhinoCompute.Grasshopper.evaluateDefinition()
Works with both .gh and .ghx files in node.js and in the browser
Construct inputs with the RhinoCompute.Grasshopper.DataTree class

Node.js example

compute = require('./compute.rhino3d.js')
fs = require('fs')

compute.url = 'https://staging.compute.rhino3d.com/'
compute.authToken = 'Bearer' + process.env.RHINO_COMPUTE_TOKEN

var buffer = fs.readFileSync('leland.gh')
var definition = new Uint8Array(buffer) // works for both .gh and .ghx

var tree = new compute.Grasshopper.DataTree('RH_IN:106:0001')
tree.append([0], ['Lorem ipsum dolor sit amet'])

compute.Grasshopper.evaluateDefinition(definition, [tree]).then(res => {
    console.log(JSON.stringify(res))
}).catch(err => {
    throw err
})

Browser example

<html>
    <head>
        <script src="compute.rhino3d.js"></script>
        <script>
            RhinoCompute.url = 'https://staging.compute.rhino3d.com/'
            RhinoCompute.authToken = RhinoCompute.getAuthToken()

            var tree = new RhinoCompute.Grasshopper.DataTree('RH_IN:106:0001')
            tree.append([0], ['Lorem ipsum dolor sit amet'])
            var trees = [tree]

            fetch('leland.gh')

            // .gh
            .then(response => response.arrayBuffer())
            .then(buffer => new Uint8Array(buffer))

            // .ghx
            // .then(response => response.text())

            .then(definition => RhinoCompute.Grasshopper.evaluateDefinition(definition, [tree]))
            .then(res => console.log(JSON.stringify(res)))
            .catch(err => { throw err })
        </script>
    </head>
</html>
