update readme

```

    python ./measurement_pipeline/run_csst_msc_instrument.py /path/to/config_detrending.yaml

```

* Products:

    * L1 calibrated images (detrended + cosmic rays removed)

    * Weight maps

    * Flag maps

### Run Source Injection

* Inject souces onto the L1 (detrended)

* Inject souces onto the L1 calibrated images

* modify the corresponding ```config_injection.yaml``` file to configure all running options

```

    python ./injection_pipeline/injection_pipeline.py /path/to/config_injection.yaml

```

* Products:

    * L1 calibrated images with synthetic sources injected

    * Truth catalogs for injected sources

### Run L1 Detection & Photometry pipeline

* Re-detect and redo the photometry measurements on the injected images

* CSST detection and photometry pipeline, can be used to:

    * Detect and do photometry measurements on the L1 calibrated images

    * Re-detect and redo photometry measurements on the injected images

* modify the corresponding ```config_photometry.yaml``` file to configure all running options

```

    python ./measurement_pipeline/run_csst_msc_mbi_photometry.py /path/to/config_photometry.yaml

```

* Products:

    * Detection catalogs with photometric information

    * Flux maps

    * PSF models (in psfex format)

    * Segmentation maps

    * Sky maps
