Document Grattan's (Hugh) use of data.table #2862

Awesome work by @HughParsonage. There's reference to things you can do in data.table that you can't do elsewhere, and 2 seconds vs 30 mins. Would be great to do a proper benchmark and write up where data.table is being used to its fullest and compare to alternatives like dplyr and SQL. It could be a page on the wiki, or an article, or both. It could be linked from our homepage. https://www.msn.com/en-gb/finance/other/coalitions-tax-plan-more-than-half-of-cuts-will-go-to-wealthiest-20-25-analysis-finds/ar-AAx3bzK https://twitter.com/MattDowle/status/994637549023838208 https://twitter.com/hughparsonage/status/994639695819653120 https://twitter.com/hughparsonage/status/994640283697496068 https://github.com/HughParsonage/grattan/blob/master/R/income_tax.R

@mattdowle Would something like https://hughparsonage.github.io/grattan/articles/datatable-implementation.html be a useful reference? Kept it short and to the point.
