Resolve "Get image metadata as dict"

Closes #49 (closed)

The returned app.metadata returns something like:

{

    "DriverShortName": "GTiff",

        0.0,
        -6.0
    ],
    "LowerLeftCorner": [
        760056.0,
        6944268.0
    ],

>>> img = pyotb.Input(r"C:\Users\vince\Geom\SDGSAT\KX10_GIU_20211106_E3.68_N48.11_202200120793_L4A_A_PXS.tif")
