[Feature request] Add parsing for extension dependencies

[rokuz]

At the moment, in extension's depends we can get something like:

VK_KHR_get_physical_device_properties2,VK_VERSION_1_1
(VK_KHR_get_memory_requirements2+VK_KHR_get_physical_device_properties2),VK_VERSION_1_1
((VK_KHR_get_physical_device_properties2,VK_VERSION_1_1)+VK_KHR_depth_stencil_resolve),VK_VERSION_1_2
VK_VERSION_1_1
(VK_KHR_spirv_1_4,VK_VERSION_1_2)+VK_KHR_acceleration_structure
VK_KHR_external_semaphore
VK_KHR_get_physical_device_properties2,VK_VERSION_1_1
(VK_KHR_get_physical_device_properties2,VK_VERSION_1_1)+VK_KHR_surface+VK_KHR_get_surface_capabilities2+VK_KHR_swapchain
((VK_KHR_synchronization2+VK_KHR_spirv_1_4+VK_EXT_extended_dynamic_state),VK_VERSION_1_3)+VK_KHR_maintenance5+VK_KHR_pipeline_library

It would be really nice if it would be presented in the format easier accessible via Python.
Thanks in advance!
