Add basic support for ATmega64
Pull in the ATDF file from Microchip and add all the necessary plumbing
around the code-base to make it compile. Not tested against real
hardware and no device-specific patches are included yet.

interrupts: Fix sed expressions for parsing interrupt list
The format for the interrupt sources changed which silently made
gen-intr-lut.sh no longer generate any interrupt names. Fix the
expressions so interrupt names are recognized again and the macro
can be used for generating interrupt definitions again.

make: Use a patchfile instead of weird sed expr
As reported in issue #24 the sed(1) expression used to patch the generated
`mod.rs` does not work on MacOS (BSD sed). Instead, use patch(1) and a small
patchfile to accomplish the same task.

gen-intr-lut: Switch to /usr/bin/env bash as interpreter
The location of the `bash` binary can vary between systems. Switch to
`/usr/bin/env bash` which is the recommended way to do it.

Fix compatibility with svd2rust 1.16.1
svd2rust now generates a module containing generic descriptions which
the individual register definitions are based on. Fix the code
generation to deal with this module.

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)
