Simplifying generated variable names and a new uniqueization method

[jiwonz]

Similar to roblox-ts, it seems like it would be possible to simplify the generated variable names and make them unique by adding a number to the end if they were used in the input code.

An example from roblox-ts:

import { CollectionService } from "@rbxts/services";

for (const obj of CollectionService.GetTagged("Lava")) {
	if (obj.IsA("BasePart")) {
		let _result = "i take";
		let _result_1 = "uniqueness";
		let _result_2 = "of _result_x from roblox-ts";
		obj.Touched.Connect(part => part.Parent?.FindFirstChildOfClass("Humanoid")?.TakeDamage(100));
	}
}

-- Compiled with roblox-ts v3.0.0
local TS = _G[script]
local CollectionService = TS.import(script, script.Parent, "include", "node_modules", "@rbxts", "services").CollectionService
for _, obj in CollectionService:GetTagged("Lava") do
	if obj:IsA("BasePart") then
		local _result = "i take"
		local _result_1 = "uniqueness"
		local _result_2 = "of _result_x from roblox-ts"
		obj.Touched:Connect(function(part)
			local _result_3 = part.Parent
			if _result_3 ~= nil then
				_result_3 = _result_3:FindFirstChildOfClass("Humanoid")
				if _result_3 ~= nil then
					_result_3 = _result_3:TakeDamage(100)
				end
			end
			return _result_3
		end)
	end
end
return nil
