Version 0.11.0

• add strong Fortran value & type representation at Language.Fortran.Repr
  (currently unused) (#235, @raehik)
  • operations are accurate to actual Fortran compiler behaviour e.g. integers
    are stored fixed-width based on kind, so overflow behaviour is free
  • can recover a value's precise type (e.g. INTEGER(8), including kind) via
    pattern matching
• bump minimum compiler version to GHC 9.0
• improved comment handling in fixed form lexer: parse more comment syntax,
  case sensitive, parse beyond column 72 (#237, @RaoulHC)
• allow ExpDataRef constructor in varName (fixes a crash in type analysis
  #238)
• add Annotated, Spanned instances for intermediate AST data type
  ArgumentExpression
• export statement-level "pre-prepared" parsers (previously, you would have to
  define the parser yourself using parser utils and the Happy parser export)
• export Language.Fortran.Parser.byVerFromFilename :: Parser (ProgramFile A0), a replacement for the removed
  Language.Fortran.Parser.Any.fortranParser
