Wire EPPROM never sync to client, and inefficient storage method

[AlexALX]

Describe the bug

This is very old story from #1338 (comment)

1. Basically during rewrites it seems completely disabled any btns in stool, they just do nothing.

Look here:

wire/lua/wire/stools/hdd.lua

Line 80 in 61691f7

concommand.Add("wire_hdd_uploaddata", function(player, command, args)

All code block are disabled, so it never sync in this way anymore.

2. It stores data in very inefficient way. for 256KB hdd with 32 blocks it will make 8192 .txt files in data/wireflash, each file are 744 bytes to store just 128 bytes real data. I think block should be higher to reduce that, and instead of storing using string.rep(" ",24-string.len(floatstr)) it might write data as binary. Also it even can use compression to save space.

3. after re-paste it i have data loss, there is CRITICAL issue with not writting last index from cache! created pull wire EEPROM doesn't write last index from cache! #3696 separately

4. Writting speed are slow, only 128 bytes per sec (32 blocks x 0.25 sec think func), so full capacity of 256kb will be written by 2048 seconds ~34 minutes. There is fallback on entity remove, which flushes all content instantly to disk, but making lag if there is a lot of data left.
