-`PcrEvent`/`PcrEventInputs` impl`Align`,`Eq`, and`PartialEq`.

- Added`PcrEvent::new_in_box` and`PcrEventInputs::new_in_box`.

-**Breaking:**`uefi::helpers::init` no longer takes an argument.

- The lifetime of the`SearchType` returned from

The old`MemoryMap` was renamed to`MemoryMapOwned`.

-`pub fn memory_map(&self, mt: MemoryType) -> Result<MemoryMap>` now returns

a`MemoryMapOwned`.

-**Breaking:**`PcrEvent::new_in_buffer` and`PcrEventInputs::new_in_buffer`

now take an initialized buffer (`[u8`] instead of`[MaybeUninit<u8>]`), and if

the buffer is too small the required size is returned in the error data.
