Feature Request: Default Font and Default Sound (Or ability to play arbitrary sounds based on frequencies)

[Aplosion]

When copy-pasting the code for Breakout, It wasn't immediately obvious where the fonts and sounds were in the repo, and there's no default font, so the game just skips rendering text and throws an error in console when no fonts can be loaded. Macroquad has a default font, so I think we should have one too.

As for sound, a built-in sound to test with would be fine, but I'd prefer a play_frequency(hertz,duration) method so that you can do math to the hertz directly and make interesting effects without needing to import anything. A OS-agnostic https://docs.python.org/3/library/winsound.html winsound-alike should? be fairly easy to implement.

https://www.seventhstring.com/resources/notefrequencies.html using this chart or similar and either code like this:

Not sure why code fences aren't working!
`#python 3
import time
import winsound

def note(name):
octave = int(name[-1])
PITCHES = "c,c#,d,d#,e,f,f#,g,g#,a,a#,b".split(",")
pitch = PITCHES.index(name[:-1].lower())
return int(440 * 2 ** ((octave - 4) + (pitch - 9) / 12.))

sequence = [("a3",8),("b3",8),("c4",256),("c#4",8),(None,1),("d#4",4),("e4",4),("f4",4),
("f#4",4),("g4",4), ("g#4",4),("a4",4),("a#4",4),("b4",4),("c5",4),]

#using the second number in the tuples as a nth note. 1 = whole note 2 = half note, etc.

for (notename, denominator) in sequence:
length = 1/denominator
if notename:
winsound.Beep(note(notename), int(length*1000))
else:
time.sleep(length)`

(Searching didn't bring anything up, hopefully this isn't a repeat)

Default fonts are discussed in #1017 and #1325 :) As discussed in #1790, the consensus seems to be that system fonts are a good way to go, but we need to think about how exactly we want to do that. cosmic_text has since been released as well: we should check if they have font handling.

A simple API to play a sound is new and valuable though: can you make an issue for it? There's an Enhancement issue template for this :)
