String interpolation cuts string literals at \0 in some cases

[Suzanna-Linn]

A literal including \0 and a expression:

-- SLua, Beta Grid
print(#`test\0ing{1}`)  -- > 4

Works well in Luau:

-- Luau, Roblox Studio
print(#`test\0ing{1}`)  -- > 9

It could be that Luau is already solving it, if it uses this code:

SLua:

slua/Compiler/src/Compiler.cpp

Lines 1962 to 1965 in fed1a35

	if (formatString.empty())
	formatStringIndex = bytecode.addConstantString({"", 0});
	else
	formatStringIndex = bytecode.addConstantString(sref(names.getOrAdd(formatString.c_str(), formatString.size())));

Yeah this one's known, will be fixed once there's a more stable Luau to upgrade to
