[Feature Request]: rename package name

[Yunuuuu]

Feature description

There already has a R packge named falcon in CRAN: https://cran.r-project.org/web/packages/falcon/index.html. We cannot install two packages with the same name

• Option 1: Herald (To be a sign that something important, and often good, is starting to happen, or to make something publicly known, especially by celebrating or praising it. - https://dictionary.cambridge.org/dictionary/english/herald)

• Option 2: Touchstone (An established standard or principle by which something is judged. - https://dictionary.cambridge.org/dictionary/english/touchstone)

another idea: {cardinal}

rationales: 1) we plan to shift falcon to an ARD-driven table engine/package, and 2)try to follow the bird theme, and "cardinal" has the word "ARD" in it

@telepath37 we're good to proceed with the rename to cardinal - it has been approved by the dev team as well.
