Include 'accepted' pronunciation for certain function/package strings

[matt-dray]

It may be beneficial, but again very opinionated, to include parsing of certain strings and function, variable and package names. For example:

• the xaringan package could be 'sharingan' and ggplot2 could be 'jee jee plot 2'
• is.numeric() could be 'is dot numeric', as_factor() could be 'as underscore factor'

Maybe camel case cold be split apart, so actionButton is split into 'action button', or something.
