lldebugger changes the slash in file paths in debug.traceback() when active

[tyoeer]

When using debug.traceback(), the slashes in the file paths change from / to \ when the debugger is started.
This is an issue because I was string pattern matching the traceback to only get the relevant part, and the slash change actually caused that to fail all the way up into a crash.

Minimal reproduction code (using LÖVE):
In main.lua:

require("test.test")

In test/test.lua:

print(debug.traceback())
require("lldebugger").start()
print(debug.traceback())

Output:

stack traceback:
	test/test.lua:1: in main chunk
	[C]: in function 'require'
	main.lua:1: in main chunk
	[C]: in function 'require'
	[love "boot.lua"]:316: in function <[love "boot.lua"]:126>
	[C]: in function 'xpcall'
	[love "boot.lua"]:355: in function <[love "boot.lua"]:348>
	[C]: in function 'xpcall'
	[love "boot.lua"]:370: in function <[love "boot.lua"]:337>

stack traceback:
	test\test.lua:3: in main chunk
	[C]: in function 'require'
	main.lua:1: in main chunk
	[C]: in function 'require'
	[love "boot.lua"]:316: in function <[love "boot.lua"]:126>
	[C]: in function 'xpcall'
	[love "boot.lua"]:355: in function <[love "boot.lua"]:348>
	[C]: in function 'xpcall'
	[love "boot.lua"]:370: in function <[love "boot.lua"]:337>

I'm using LÖVE 11.4 on WIndows 10 if that matters.
