#ENABLE_UNSAFE_OPTIMIZATIONS
Added new global flag to enable unsafe optimizations:
This will disable several safety features in microncleus to save around
40 more bytes
Disabled features:
* Stack pointer and SREG initialization in CRT
* Client side reset vector patching
* USB collision detection. Micronucleus will not work reliability with
hubs if this is disabled.
See t85_aggressive configuration for usage examples.
