Language options

[tohlh]

This PR aims to add language options to Source Academy missions. The use case for now is allowing instructors to configure type strictness in Source Typed variants.

Library Schema

The Library Schema is used to describe the language configuration for an assessment question. An optional field languageOption is added into the Library schema to achieve our objective.

XML Parsing

This changes the XML parser. Specifically, the XML tags <DEPLOYMENT> and <GRADERDEPLOYMENT> are renamed to <PROGRAMMINGLANGUAGE>, <GRADERPROGRAMMINGLANGUAGE>, as per discussion. <LANGUAGEOPTIONS> tags are also added to configure programming language flags.

Example usage of <PROGRAMMINGLANGUAGE>, <GRADERPROGRAMMINGLANGUAGE> and <LANGUAGEOPTIONS> tag:

<PROGRAMMINGLANGUAGE chapter="2" variant="typed">
  <OPTION key="typedAllowAnyInVariables" value="false" />
  <OPTION key="typedAllowAnyInParameters" value="false" />
  <OPTION key="typedAllowAnyInReturnType" value="false" />
  <OPTION key="typedAllowAnyInTypeAnnotationParameters" value="false" />
  <OPTION key="typedAllowAnyInTypeAnnotationReturnType" value="false" />
</PROGRAMMINGLANGUAGE>

<GRADERPROGRAMMINGLANGUAGE chapter="2" variant="typed">
  <OPTION key="typedAllowAnyInVariables" value="false" />
  <OPTION key="typedAllowAnyInParameters" value="false" />
  <OPTION key="typedAllowAnyInReturnType" value="false" />
  <OPTION key="typedAllowAnyInTypeAnnotationParameters" value="false" />
  <OPTION key="typedAllowAnyInTypeAnnotationReturnType" value="false" />
</GRADERPROGRAMMINGLANGUAGE>

These changes are not breaking and should work with existing assessments. For future assessments, XMLs have to be changed.
