Using bokeh - halts on missing yaml module

[larstuff]

Hi. I see that both numpy and bokeh are in the wasm, but when I try using bokeh, pygbag halts with the error:

1202: want='yaml' found : False
PKG NOT FOUND : want='yaml', resume=<function at 0x1864780>, ex=ModuleNotFoundError("No module named 'yaml'")

Bokeh script works ok after I alter the script to go 'pygbagging', and shows a html file immediately in the browser. Script is simple:

`import numpy as np
import yaml
from bokeh.plotting import figure, show
import asyncio

async def main():
x = np.arange(0, 10, 1)
y1 = x ** 2
y2 = x ** 3
y3 = x ** 4

p = figure(title="Simple line charts", x_axis_label="x", y_axis_label="y")

p.line(x, y1, legend_label="x2", line_width=2, color="red")
p.line(x, y2, legend_label="x3", line_width=2, color="green")
p.line(x, y3, legend_label="x4", line_width=2, color="blue")

show(p)
await asyncio.sleep(0)

asyncio.run(main())`

The script does have the correct indentation, but pasting it into github messed it a little bit up. Is there any chance yaml will be added?

transfering issue to https://github.com/pygame-web/pkg-porting-wasm
i guess yaml is binary and rely on libYaml

a pyyaml wheel ( in pure python mode ) has been added for testing
use --git option on pygbag cmdline
