/stats command and improvements to the /advancement command (Java Edition)

A /stats command could be useful when managing servers and creating datapacks, working in a way similar to /advancement

Syntax

/stats [pause|resume|get|set|add|reset] [player] [statistic] [value]

• pause stops tracking a statistic. The [statistic] argument is optional, so /stats pause @s would pause all statistics, while /stats pause @s minecraft:animals_bred would only pause that statistic.

• resume resumes tracking. It works the same way as pause.

• get returns the current value of a statistic.

• set sets a statistic to a specific value.

• add adds or subtracts a value from a statistic.

• reset resets a statistic.

Only get, set, and add would require [statistic]

Only set and add would require [value]

Examples:

/stats pause @s

/stats resume @s

/stats reset @s

/stats get @s minecraft:damage_taken

/stats set @s minecraft:fill_cauldron 0

/stats add @s minecraft:walk_one_cm 160

/stats add @s minecraft:eat_cake_slice -27

/stats reset @s minecraft:trigger_trapped_chest

I would also suggest adding pause and resume to /advancement:

/advancement [pause|resume|grant|revoke] ...

For example:

/advancement pause @s

/advancement resume @s

/advancement pause @s only minecraft:story/mine_stone

pause would temporarily stop advancements from being tracked and awarded, while resume would enable them again.
