Currently the parameters for abcjs are hard-coded to:

{
  "responsive": "resize"
}

This prohibits the user from using other options, such as tablature.

For example, if I want to render this violin tab in the abcjs documentation, I cannot do it because there is no way to set the abcjsParams to:

{
  "tablature": [
    { "instrument": "violin" }
  ]
}

This PR allows users to manually specify abcjsParams to use by prefixing the content with:

%%params {tablature: [{instrument: "violin"}]}

Using this, the example now renders correctly:

%%params {tablature: [{instrument: "violin"}]}

Please let me know if there is another approach to get the abcjsParams passed into the render function that you would prefer.
