I'm curious if there's a way to change the build context when running earthly.

i.e. my repository is organized as such:

/repo_root
|- ./docker
 |- Earthfile
 |- configurations, scripting, etc
|- ./src
 |- code I want to COPY into my container

docker build allows for you to specify a build context of .. for this particular use-case, curious if Earthly supports anything similar or if the build context is purely an artifact of the placement of the Earthfile
