feat: allow chainable msg filters; add MouseThrottleFilter

[lrstanley]

Changes in this PR

Made some tweaks to message filtering, as I think this will help others. If y'all don't think it will be too useful, or would rather approach it a different way, feel free to close this out.

• Converted WithFilter(filter) to WithFilters(filters...) to allow chainable filters, with a MsgFilter type to clean things up a little.
• Added an out-of-box MouseThrottleFilter filter, to cover throttling of high-frequency mouse messages. This logic is also used in crush here, and one of my apps, and I suspect such functionality will help others improve performance when they don't need the high-frequency tracking.
