TODO: Add functionality to flush a demo chunk

[Bash-09]

@cgcha mentioned:

The method i did for echo spamming was similar to this

alias test_a echo "testtesttesttesttesttesttesttesttesttesttesttesttesttesttesttest"`

alias test_b "test_a;test_a;test_a;test_a;test_a;test_a;test_a;test_a;test_a;test_a;test_a;test_a"

alias test_c "test_b;test_b;test_b;test_b;test_b;test_b;test_b;test_b;test_b;test_b;test_b;test_b;test_b;test_b;"

in order to scale quickly and because there's a limit to how long an individual echo can be. doing this, you can chain an echo that basically immediately flushes the buffer, but will cause a noticable stutter. However, i created a macro that would press a button every 300 ms and I used that to echo spam, and I didn't notice any degradation to performance (but this should be tested on more systems)
