Add configurable filter for different log 'types' in browser extension options

Copied from https://github.com/apache/flagon-useralejs/issues/47

Currently the browser extension has limited configurability through /UserAleWebExtension/options.js--userAleHost, userAleScript, toolUser, toolName, toolVersion. As such, the embedded userale-X.x.x.js script logs everything. It would be good to embed a filter in ./background.js that receives user inputs through opstionsPage.js and options.js. A nice example example of a filter can be found in our /example dir:

window.userale.filter(function (log) { var type_array = ['mouseup', 'mouseover', 'mousedown', 'keydown', 'dblclick', 'blur', 'focus', 'input', 'wheel']; var logType_array = ['interval']; return !type_array.includes(log.type) && !logType_array.includes(log.logType); });
Would be nice to include a form object that would allow users to add (through drop down or simple text input) event 'types' (e.g., mousedown, mouseup, mouseover) and log 'types' (e.g., 'raw', 'interval') (aside: maybe toggle for 'interval') to exclude from the browser extension log stream.

Start by reading UserAleWebExtension/background.js, optionsPage.js, and options.js to trace how extension settings reach the embedded logger. Compare the requested behavior with the filter example in the example directory. Done means users can configure excluded event types and log types, including the proposed interval option, and those settings affect the browser extension log stream.
