Fix: Use float defaults (0.0) in APoint to ensure correct type inference & Feature : added send_command() and send_commands() functions

🛠 Release Notes – v0.1.10

✨ New Features

• Added send_command() and send_commands() methods
  These methods allow you to programmatically send command strings to the AutoCAD command line:

  • send_command(command_string) — sends a single command (asynchronously).
  • send_commands(commands) — sends a sequence of command strings in order.

  ⚠️ Note: These operations are asynchronous; commands requiring user interaction or long processing may need delays or alternative handling.

🐛 Bug Fixes

• Fixed default value types in APoint constructor
  Changed default x, y, z values from 0 to 0.0 to ensure proper float type inference. This resolves unintended behavior where arguments were inferred as integers.
  Thanks to @Thomas737 for spotting this!
