Need to find a better way to cancel the timer once yt-navigate-start / yt-navigate-cache is triggered.

Currently I just use the url to detect which is not sufficient. (url != watch => bypass)

Fixed in v0.9.0

• Added FIX_avoid_incorrect_video_meta_emitterBehavior to cancel the previous scheduling
• added pageSetupState to check the immediate state of page loading when the function is called by the scheduler during that state (use setTimeout to delay the call)
• added videoPlayingY to obtain the playing video at the time of meta updating (can work in miniview playing)
• LimitedSizeSet is added so that oldest entries will be removed to avoid overflowing of continuation records
• added sha1Hex and continuationLog for the message log, if the user is using macOS and latest browser (very fast computer) [as continuation key are so similar; difficult for debug]

---

• Added coding for scheduleInitialUpdatedMetadataRequest
• Rewrote the coding for fetchUpdatedMetadata, sendServiceAjax_, getCancellableNetworkPromise_

---

There are several mechanisms to co-working together in these 4 functions.

• immediate state checking (pageSetupState) with delay calling
• continuation and url matching; store the last key and cache the keys used before.
• uncertain continuation determined in fetchUpdatedMetadata will be delayed by 8000ms or 800ms to wait for new continuation being sent to fetchUpdatedMetadata in the next call
• mfvContinuationRecorded and mfyContinuationIgnored for past multiple observed records
• ... and more
