[cyacc] Example given is wrong, should use turbofish

[lord-ne]

In the cycle-accurate implementation (#28), the example code in the README has delay_ms<1000000>();. However, if you actually try to compile that line, you get the following error:

error: comparison operators cannot be chained:
  |
9 |     delay_ms<1000000>();
  |             ^       ^
  |
help: use `::<...>` instead of `<...>` to specify lifetime, type, or const arguments
  |
9 |     delay_ms::<1000000>();
  |             ++

Changing it to delay_ms::<1000000>(); fixes the issue. Thus, that example (and any others) should be updated to use the "turbofish" operator ::< >
