minor patches

as outlined in #8

Thanks for this great library! Helped me a lot.
I think the following could be done to make it even better.
I already added my suggested improvements.

change await function

# last bit (1) is BUSY bit in stat. reg. byte (0 = not busy, 1 = busy)
trials = 0
while 0x1 & self.spi.read(1, 0xFF)[0]:
    trials += 1
    if trials > 20:
         raise Exception("Can't read from device")
    sleep(0.1)

Current code can lead to infinite loop and you should do somethingl like above

writeblocks should not check block length
You check block length and raise warning if not satisfied.
This is against spec (https://docs.micropython.org/en/latest/library/os.html).
Also gives issue if you write a file raw to memory with a size not equal to multiple of blocks

if len(buf) %buffsize != 0:
    buf += bytearray((buffsize-(len(buf)*[255]))
# NOTE: in my final fix I remove the appended bytes

don't break just raise warning
I would do something like this in the identify function.

if mf != 0xEF or mem_type not in [0x40, 0x60, 0x70]:
    # Winbond manufacturer, Q25 series memory (tested 0x40 only)
    print(f"manufacturer ({}) or memory type ({}) note tested")

Thank you for your contribution @hstarmans

I haven't yet updated this package with the latest contribution requirements/guidelines as done here in the package template

May you could update the changelog.md and the winbond/version.py file?

[hstarmans]

Added changes as requested!

Nice, we're almost there. Just the flake8 style warnings need to be fixed

Sure, I added a config for pre-commit so a check is carried by git before a push is made to the repo. This is also recommended by micropython. The config is minimal. For a more extended example see https://github.com/sktime/sktime/blob/main/.pre-commit-config.yaml .
