Add support for IANA approved mime-type "video/lottie+json" and extension ".lot"

[kudanai]

As part of efforts by LAC, IANA has approved the video/lottie+json type and .lot extension for use with Lottie animations. In light of this we should consider adding the relevant recognition in the library.

Enhancement. lottie-android should recognize .lot and the video/lottie+json mime type on the network loader

Describe the solution you'd like

• pick up .lot from storage, and inside .zip|.lottie files (if applicable)
• recognize video/lottie+json in the network pipeline

In both these instances, they should be treated the same as .json would be.
for clarity, this in now way disqualifies the usage of .json to transport animations. The .lot extension is in addition to the existing mechanism
