Remove backward compatibility and change package structure to pandas_ta_classic

[Copilot]

This PR removes backward compatibility and restructures the package to use pandas_ta_classic as the Python package name, aligning with the PyPI package name pandas-ta-classic.

Key Changes

Package Structure

• Renamed Python package from pandas_ta to pandas_ta_classic
• Updated setup.py to use new package structure (pandas_ta_classic.* modules)
• Removed backward compatibility - old import syntax no longer works

Import Syntax Change

• New required import: import pandas_ta_classic as ta
• Old import (no longer works): import pandas_ta as ta
• PyPI package name remains pandas-ta-classic

Updated Documentation

• All README examples now use import pandas_ta_classic as ta
• GitHub issue templates updated with new import syntax
• Examples and custom indicator documentation updated
• Installation command remains: pip install pandas-ta-classic

Breaking Change

This is a breaking change that requires users to update their import statements:

# Before (no longer works)
import pandas_ta as ta

# After (required)
import pandas_ta_classic as ta

# Usage remains the same
df.ta.sma(length=20)
ta.rsi(df.close)

Validation

• ✅ Package installs successfully as pandas-ta-classic
• ✅ New import syntax import pandas_ta_classic as ta works correctly
• ✅ Old import syntax fails as expected (no backward compatibility)
• ✅ Core functionality (SMA, RSI, MACD, DataFrame extension) works properly
• ✅ All internal package imports updated and functional

This change establishes a clear naming convention where both the PyPI package name and Python package name use the pandas-ta-classic identifier.

The regex replacement uses a raw string with extra escaping. The pattern should be r"\g<1> \g<2>" or the original "\g<1> \g<2>" but not both. The current format r"\g<1> \g<2>" will produce literal backslashes in the output.

The comment references the old package name in the explanation. It should be updated to reflect the new package structure consistently.

[nitpick] This comment line is part of the same docstring and maintains consistency with the package name update, but the explanation could be clearer about what the circular import issue actually is.
