Using UUIDs for unique tagnames

• Changing creation of unique persistent tag names from timestamp with milliseconds to using uuids to fix tag collision in parallel threads or immediately consecutive calls

Escaping non-ascii characters

• Escaping synchronized non-ascii characters in TagGroup keys and string values and unescaping
  them in python again to prevent DigitalMicrograph crashing due to encoding problems
• Removing deprecated structure definition of TagGroups and TagLists
• Adding conversion support from dm-script UInt32 to python int and dm-script UInt16 to python
  int

Adding get_persistent_tag() and remove_global_tag() function

• Adding remove_global_tag() with example in README
• Adding debug_file can be any file object which includes sys.stdout to directly print out the
  code to execute
• Adding get_persistent_tag() with example in README
• Adding deprecation warning when defining the strucutre of TagGroups or TagLists in the
  readvars in the exec_dmscript() function

Improving convert_to_taggroup()

• Adding invalid_taggroup_key_characters tuple that contains character that are invalid for
  DigitalMicrograph TagGroup key names
• Adding replace_invalid_chars parameter to convert_to_taggroup() to offer automatic replacing
  of invalid TagGroup key names
• Improving raised errors and their message in convert_to_taggroup() to explain better what the
  error is about
• Improve doc comment of convert_to_taggroup()
• Fix convert_to_taggroup() function by fixing call of a non-existing function due to a typo

Adding convert_from_taggroup() function

• Adding __file__ variable is now always given in dm-script containing the current dm-script file
  path
• Adding ingore markers @execdmscript.ignore.start and @execdmscript.ignore.end to allow code
  that is only executed in direct dm-script calls
• Adding convert_from_taggroup() function that converts DigitalMicrograph.Py_TagGroup to
  dicts, lists which is the opposite function to convert_to_taggroup()
• Adding helper documentation in README
• Adding examples for get_dm_type() and get_python_type()
• Adding examples for escape_dm_variable() and escape_dm_string()
• Adding examples for convert_from_taggroup() and convert_to_taggroup()

Adding convert_to_taggroup() function

• Adding convert_to_taggroup() function that converts dicts, lists and tuples to a
  DigitalMicrograph.Py_TagGroup directly.
• Changing imports in __init__.py to import everything

Fix synchronizing of invalid TagGroups

• Fixing error when synchronizing TagGroups and the TagGroup is invalid in dm-script

Improving Readme and examples

• Rewriting big parts of the README to make it more understandable
• Adding more and easier examples

Big thanks to BmyGuest

Add separate dm-script thread execution

• Adding __version__ to module
• Adding VERSION file
• Adding separate_thread option to allow execution of dm-script in a separate dm-script thread

Improve dm-script errors

• Adding new error class DMScriptError
• Checking dm-script execution on runtime dm-script errors, displaying them to the user with
  corrected line numbers
