Adds `Util.DebugExecutionTime()`, which returns a table of
`function_name: milliseconds`, in which each function's execution time
is averaged over all time.
You can call this function like so:
```lua
-- event to print the debug times
MP.RegisterEvent("printStuff", "printStuff")
-- prints the execution time of all event handlers
function printStuff()
print(Util.DebugExecutionTime())
end
-- run every 5 seconds (or 10, or 60, whatever makes sense for you
MP.CreateEventTimer("printStuff", 5000)
```
Pretty print function:
```lua
function printDebugExecutionTime()
local stats = Util.DebugExecutionTime()
local pretty = "DebugExecutionTime:\n"
local longest = 0
for name, t in pairs(stats) do
if #name > longest then
longest = #name
end
end
for name, t in pairs(stats) do
pretty = pretty .. string.format("%" .. longest + 1 .. "s: %12f +/- %12f (min: %12f, max: %12f) (called %d time(s))\n", name, t.mean, t.stdev, t.min, t.max, t.n)
end
print(pretty)
end
```
`Util.DebugExecutionTime()` returns a table, where each key is an event
handler function name, and each value is a table consisting of `mean`
(simple average), `stddev` (standard deviation aka mean of the
variance), `min` and `max`, all in milliseconds, as well as `n` as the
number of samples taken.
