pip install fails (m1 mac, aarch64) and workaround

[jwmay2012]

mprofile is failing to compile when I try to pip install pyproff inside a container, running on Apple M1 Max.

Dockerfile

FROM python:3.9-slim

RUN apt-get -qqy update
RUN apt-get install gcc g++ -y

RUN pip install -U pip
RUN pip install pypprof

docker build .

I don't know much about this problem, but a workaround I've found is to change the initial container image to
FROM --platform=linux/amd64 python:3.9-slim
as it usually defaults to aarch64.
There's also this DOCKER_DEFAULT_PLATFORM=linux/amd64

I felt compelled to document and share this.

Well. I'm trying to use pypprof for a Django application and apparently my 'fix' --platform=linux/amd64 breaks Django completely in the local environment.

Does anyone have any ideas on how to get this compiling in aarch64?

Thanks

Opened a PR to fix this #5. I haven't tested it too much yet, so please use with caution.
