Generate Text and Documents with the Tera Templating Engine

The 'tera' package uses 'extendr' to provide access to Vincent Prouillet's 'Tera' templating engine in Rust. Users mainly interact with a Tera R6 object, which serves as a template library with encapsulated methods for rendering templates with a given context. Template syntax supports additional logic, including built-in filters, tests, and functions, as well as loops, conditions, and inheritance. Documentation for Tera's templating syntax can be found at < https://keats.github.io/tera/>.
