UMDP3 Checker

Issues

• Fix incorrect detection of Lowercase or CamelCase variable names only

  LOGICAL           :: flag_precip_sym = .FALSE.  ! due to the presence of .FALSE.

• Clarify output in verbose-mode

  1 : UPPERCASE variable name at line(s): 40, 43, 48, 49, 50 instead of
  1 : UPPERCASE variable name : [40, 43, 48, 49, 50]

• Scan only what needs to be scanned instead of all files when --file-type flag is present

  umdp3_conformance.py --path <repo> --file-type Fortran --fullcheck
