New JSON dump format

Browse Source 
Unified across VMA and D3D12MA.
Updated Python script for visualization - now called GpuMemDumpVis.py.

Also a fix for bug in EXTENSIVE defragmentation algorithm - see #232

@ -59,7 +59,7 @@ Additional features:
- Statistics: Obtain brief or detailed statistics about the amount of memory used, unused, number of allocated blocks, number of allocations etc. - globally, per memory heap, and per memory type.
- Debug annotations: Associate custom `void* pUserData` and debug `char* pName` with each allocation.
- JSON dump: Obtain a string in JSON format with detailed map of internal state, including list of allocations, their string names, and gaps between them.
- Convert this JSON dump into a picture to visualize your memory. See [tools/VmaDumpVis](tools/VmaDumpVis/README.md).
- Convert this JSON dump into a picture to visualize your memory. See [tools/GpuMemDumpVis](tools/GpuMemDumpVis/README.md).
- Debugging incorrect memory usage: Enable initialization of all allocated memory with a bit pattern to detect usage of uninitialized or freed memory. Enable validation of a magic number after every allocation to detect out-of-bounds memory corruption.
- Support for interoperability with OpenGL.
- Virtual allocator: Interface for using core allocation algorithm to allocate any custom data, e.g. pieces of one large buffer.

* `INPUT_FILE` - path to source file to be read, containing dump of internal state of the VMA library in JSON format (encoding: UTF-8), generated using `vmaBuildStatsString()` function.
* `INPUT_FILE` - path to source file to be read, containing dump of internal state of the VMA/D3D12MA library in JSON format (encoding: UTF-8/UTF-16), generated using `vmaBuildStatsString()` and `D3D12MA::Allocator::BuildStatsString()` functions.
* `OUTPUT_FILE` - path to destination file to be written that will contain generated image. Image format is automatically recognized based on file extension. List of supported formats can be found [here](http://pillow.readthedocs.io/en/latest/handbook/image-file-formats.html) and includes: BMP, GIF, JPEG, PNG, TGA.
