Version 2.0.0

• upgrade to a2lfile 2.0.0
  • fix the definition of AR_COMPONENT
  • don't remove valid elements during cleanup
• Create and update INSTANCEs and TYPEDEF_MEASUREMENTs if the file version is 1.7.1 and --enable-strucutres is set
• Insert whole arrays of MEASUREMENTs and CHARACTERISTICs instead of separate items for each element if the array elements have a simple datatype
• Items can now be inserted based on the containing elf section
• Debug data reader improvements - extracted information should now be better and more complete
  With assistance and fixes by @oleid - Thanks!
• Support XCP IF_DATA up to version 1.4 (previously only version 1.2 was supported)
• Use new array notation if the file version is 1.7.0 or newer - "[x]" instead of "._x_"
• Fix the BIT_MASK attribute for big-endian targets
• Remove a stray debug print that caused message spam while inserting CHARACTERISTICs
