Support for Cached Playback

[akasaki1211]

Currently, enabling cached playback causes incorrect behavior in the dynamics system. Although the documentation advises disabling cached playback, we plan to improve this in the following steps:

1. Automatically disable cached playback when a boneDynamicsNode is present.
2. (After completing necessary tests) Add support for dynamics caching so that the system functions correctly even when cached playback is enabled.

In commit a57a546, automatic disabling of Cached Playback was implemented. This change is included in version 0.4.2.

Note: Commit a0b1d26, which attempted to support Cached Playback, caused frequent crashes and has therefore been removed from the dev branch and moved to a separate branch for isolation. Investigation will continue.

In commit 9ec6796, Cached Playback is now disabled only when required, based on the enable attribute. This change is included in version 0.4.3.
