Migration from Raster to terra packages

[Schuch666]

Most of the functions of EmissV imports from raster, the "next step" to a more stable and up-to date package is to replace raster to terra:

and

The raster package are stable and functional https://github.com/rspatial/raster/blob/master/NEWS with minimal maintenance to work using libraries from terra package

All the raster dependencies in the package EmissV functions:

• gridInfo() -> read WRF-Chem grid information
• read() -> read emissions from netcdf inventory
• rasterSource() -> calculate area souce
• areaSource() -> calculate area souce
• lineSource() -> calculate area souce
• pointSourve() -> calculate area souce
• emission() -> calculate emissions for the WRF-Chem model
