alexei.dolgolyov 04dd63825c Add intelligent handling for oversized photos in Telegram service ...

Implements send_large_photos_as_documents parameter to handle photos
exceeding Telegram's limits (10MB file size or 10000px dimension sum).

Features:
- Automatic detection of oversized photos using file size and PIL-based
  dimension checking
- Two handling modes:
  * send_large_photos_as_documents=false (default): Intelligently
    downsizes photos using Lanczos resampling and progressive JPEG
    quality reduction to fit within Telegram limits
  * send_large_photos_as_documents=true: Sends oversized photos as
    documents to preserve original quality
- For media groups: separates oversized photos and sends them as
  documents after the main group, or downsizes them inline
- Maintains backward compatibility with existing max_asset_data_size
  parameter for hard size limits

This resolves PHOTO_INVALID_DIMENSIONS errors for large images like
26MP photos while giving users control over quality vs. file size.
