Feature/folder structure

[miquelmassot]

Extended discussion from #47 and related issues covered in this PR (#41, #42, #46, #53)

Proposed folder structure:

<dive_folder>/image/
└── <camera_name>
    ├── params_uniform_suffix
    ├── params_altitude_suffix
    ├── params_depth_map_suffix
    ├── params_manual_suffix
    ├── corrected_uniform_mean_XX_std_YY_suffix
    ├── corrected_altitude_mean_XX_std_YY_suffix
    ├── corrected_depth_map_mean_XX_std_YY_suffix
    └── corrected_manual_gain_RR_GG_BB_sub_RR_GG_BB_suffix

And the suffix is a command-line argument that allows users to run image corrections and write them into separate folder without needing to move folders manually.
