Implement interrupts
This commit adds a new feature-flag `rt` which, when enabled, adds the
`#[interrupt]` procedural macro to define an interrupt handler. Unlike
the implementation in cortex-m, this version needs an attribute which is
the name of the chip the interrupt is for. In code, an interrupt
handler might look like this:
#![feature(abi_avr_interrupt)]
#[avr_device::interrupt(atmega32u4)]
fn INT6() {
// Do Something
}
Closes #1.

atmega328p: Add missing patches
This commit adds patches for ATmega328P by copying the commons from ATmega32U4, omitting PLL because the 328p lacks that feature (#11)

svdpatch: Add _write_constraint modifier
"_write_constraint" allows to change the write-constraint
to one of:
- "enum": Allow only enumerated values (useEnumeratedValues)
- "none": Completely remove the <writeConstraint> tag
- [min, max]: Allow only values in a certain range (this can
be used to make the bits() method safe)
Fixes #8
