Compiler conversions

[aaronpowell]

This pull request includes several changes across multiple files to improve exception handling, add new test cases, and update type conversion methods. The most important changes include adding exception handling for Python conversions, adding new test cases for collections and dictionaries, and updating type conversion methods to enhance functionality and reliability.

Exception Handling Improvements:

• Updated multiple methods to throw exceptions directly when Python errors occur, improving error reporting and debugging. (src/CSnakes.Runtime/CPython/Dict.cs, src/CSnakes.Runtime/CPython/Import.cs, src/CSnakes.Runtime/CPython/List.cs, src/CSnakes.Runtime/CPython/Object.cs, src/CSnakes.Runtime/CPython/Tuple.cs, src/CSnakes.Runtime/CPython/Unicode.cs) [1] [2] [3] [4] [5] [6]

Test Case Additions:

• Added new test cases to PyObjectTests for collections and dictionaries, ensuring the new conversion methods work as expected. (src/CSnakes.Runtime.Tests/Python/PyObjectTests.cs)

Type Conversion Enhancements:

• Updated the PyObjectTypeConverter to improve type conversion methods, including adding new methods for converting to collections and dictionaries. (src/CSnakes.Runtime/PyObjectTypeConverter.Dictionary.cs, src/CSnakes.Runtime/PyObjectTypeConverter.List.cs, src/CSnakes.Runtime/PyObjectTypeConverter.Generator.cs, src/CSnakes.Runtime/PyObjectTypeConverter.BigInteger.cs) [1] [2] [3] [4] [5]

Code Formatting:

• Improved code formatting for better readability and consistency, including adjusting indentation and line breaks. (src/CSnakes.Runtime.Tests/RuntimeTestBase.cs, src/CSnakes.Runtime.Tests/Python/PyObjectTests.cs) [1] [2]

Internal Method Updates:

• Changed access modifiers for several methods in PyObjectTypeConverter to internal, allowing for better encapsulation and testing. (src/CSnakes.Runtime/PyObjectTypeConverter.Dictionary.cs, src/CSnakes.Runtime/PyObjectTypeConverter.Generator.cs, src/CSnakes.Runtime/PyObjectTypeConverter.BigInteger.cs) [1] [2] [3]
