Wrong evaluation of ~character

[oktoberfest6]

Hi,

According to https://www.rfc-editor.org/rfc/rfc6901#section-4 the string "~01" should be evaluated to "~1" but is currently evaluated to "/"

local jsonpatch = require('jsonpatch')

local o = {
}

local operations = {
	{ op = "add", path = "/~01", value = "value" },
}

print("object before")
for k,v in pairs(o) do print(k, v) end
jsonpatch.apply(o, operations)
print("object after")
for k,v in pairs(o) do print(k, v) end

Result of execution

object before
object after
/	value

I think the two following lines in decode_token

    t = string.gsub(token,"~0","~")
    t = string.gsub(t,"~1","/")

should be swapped into

    t = string.gsub(token,"~1","/")
    t = string.gsub(t,"~0","~")

Thanks, I will look into it
