Obsolete PIO Core is used - add option to change `.platformio` dir location

The problem

Hi there!

I am a happy user of Platformio in all my projects. So i had it installed, the newest version - 6.0.1

I wanted to update my esphome devices - so i ran pip install esphome, and then esphome run mydevice.yaml

But it prints (on yellow):

esphome run mydevice.yaml
INFO Reading configuration mydevice.yaml...
INFO Generating C++ source...
INFO Compiling app...
**********************************************************************************************
Obsolete PIO Core v5.2.5 is used (previous was 6.0.1)
Please remove multiple PIO Cores from a system:

**********************************************************************************************

and then big error on red:

============================================================

An unexpected error occurred. Further steps:

* Verify that you have the latest version of PlatformIO using
  `pip install -U platformio` command

* Try to find answer in FAQ Troubleshooting section

============================================================

(i suppose because of said yellow section - because it's a downgrade version of platformio)

This is a general problem that i always had - my global platformio version was in conflict with what esphome wanted to use

I tried to solve this with virtualenv, but it is still using same $HOME/.platformio path for all of it's stuff

I fixed this temporarli for myself by setting env var PLATFORMIO_CORE_DIR to my local project dir. I tried adding core_dir to platformio_options in my yaml file, but:

Warning! Ignore unknown configuration option `core_dir` in section [env:myproject]

...it is not recognized, because it's the env section

Solution for me now, is to set PLATFORMIO_CORE_DIR every time... but it would be nice if there was an option to set this permanantly... either in each and every device .yaml file, or some new esphome.yaml config...
