Add support for spriter new scon format

[takhimi]

Currently only support scml file. I've read from lucid at brashmonkey that scon is faster than xml. I'm not sure engine capability, which is actually faster ? xml or json ?

In this case, the provided code is designed to handle SCML files, and there doesn't seem to be any implementation for directly parsing XML or JSON files. Therefore, the discussion about which format is faster is irrelevant here as the code is already optimized for SCML files.

However, generally speaking, JSON tends to be lighter and faster to parse than XML due to its simplified data structure and lower redundancy. But performance differences can vary depending on the implementation and the size and complexity of your data.

If you have flexibility in choosing the data format and efficiency is a primary consideration, you may want to consider JSON over XML. However, it's always recommended to perform performance tests in your specific environment to determine which format works best for your specific needs.
