v0.2.0

Features

• Change output format to match style of Ruff's concise style.
• Add argparse command description.
• Introduce allowed-words configuration setting which adds words to the vocabulary list.

Bug fixes

• In the previous version, a "token" would be incorrectly divided if its first character was lowercase and the second uppercase. Correcting this misinterpretation.
• In the previous verison, unwanted print statements were present. Removing those print statements.
• In the previous version, the error message when the configuration setting exclude was not an array mistakenly referred to the setting as config. Replacing word config with exclude.
• In the previous version, the program would crash if a non-string were included inside the configuration setting exclude array. Printing error message instead.
• Allow all alphabetic characters to be included in a word. Otherwise certain words with characters not in the spelling list may be split incorrectly, such as those with diacritics.
