Update Depends

[cadam00]

Updated Depends field to Depends: R (>= 4.1.0) in DESCRIPTION, so as to get rid of the CRAN note:

Version: 1.6.0
Check: DESCRIPTION meta-information
Result: NOTE
    Missing dependency on R >= 4.1.0 because package code uses the pipe
    |> or function shorthand \(...) syntax added in R 4.1.0.
    File(s) using such syntax:
      ‘chadwick_installation.R’
