Failing to parse env values for setLocation command

[prasanta-biswas]

Describe the bug
setLocation command is failing when latitude and longitude values are passed as env variables from command line

To Reproduce
Sample flow.yaml

appId: com.myapp.staging
---
- setLocation:
    latitude: ${LAT}
    longitude: ${LNG}
- launchApp

1. Start the simulator/emulator
2. Run maestro test flow.yaml -e LAT=-6.2555643 -e LNG=106.8107929
3. The Flow fails with error:

Failed to parse file: /Users/myuser/maestro/test.yaml:4
Cannot deserialize value of type `double` from String "${LAT}": not a valid `double` value (as String to convert)

Expected behavior
It should be able to accept parameters for latitude and longitude from env/javascript
