v0.6.20

• New features:
  • Better error location reporting
• Fixes bugs:
  • CLaSH.Sized.Internal.Unsigned.maxBound# not evaluated at compile-time #155
  • CLaSH.Sized.Internal.Unsigned.minBound# not evaluated at compile-time #157
  • Values of type Index 'n', where 'n' > 2^MACHINE_WIDTH, incorrectly considered non-synthesisable due to overflow
  • VHDL: Types in generated types.vhdl incorrectly sorted
  • Casts of CLaSH numeric types result in incorrect VHDL/Verilog (Such casts are now reported as an error)
