Update setup.py, installation instructions and transformer settings

[YasserElj]

1. sam2/modeling/sam/transformer.py:

   • Added warnings.simplefilter(action="ignore", category=FutureWarning) to ignore FutureWarnings.
   • Updated the settings for OLD_GPU, USE_FLASH_ATTN, and MATH_KERNEL_ON to the desired values:

     OLD_GPU = True
     USE_FLASH_ATTN = False
     MATH_KERNEL_ON = True

2. setup.py:

   • Updated package_data to include sam2_configs:

     package_data={
         "sam2_configs": ["*.yaml"],
     },

3. setup.py:

   • Updated installation instructions to include the correct commands:

     pip install git+https://github.com/facebookresearch/segment-anything-2.git
     

These changes ensure that the sam2_configs files are correctly packaged and that the transformer settings are updated as required.
