usage: require("ramfs")
this library allows you to create a file system in RAM
this can be useful in some, albeit rare cases
the API of the file system created in this way is identical to the API of the disk
this library also allows you to convert a file system to a string, for example, to write it to another medium (for example, a cardboard punched card)
you can use the vfs library to mount multiple filesystems into a single virtual filesystem

methods:

• ramfs.create(size:number):fsobj - takes the size in bytes and creates a filesystem in RAM
• ramfs.load(string):fsobj - creates a filesystem from a string dump
• ramfs.dump():string - creates a dump of the filesystem as a string. so that it can be saved for further load
• ramfs.isChange():boolean - checks the file system for changes

            --example, this code allows you to allocate a small file system in a computer data string
--despite the size of the data string of 4 kilobytes, the file system in the example is created in 2 kilobytes.
--this is done because the filesystem serializer adds its information, and there might be a shortage of space
local ramfs = require("ramfs")

local currentComputerData = getData()
local fsobj
if currentComputerData == "" then
    fsobj = ramfs.create(1024 * 2)
else
    fsobj = ramfs.load(currentComputerData)
end

local disk = fsobj.fs
