12be983487 cnn-rnn-ocr inference: switch back to beam search, only run in TF… 
- training.models.CTCDecoder: prefer beam search over greedy
  (because it is more accurate)
- training reload makefile: skip ONNX and TF-Serving conversion
  for cnn-rnn-ocr models (because these would not work)
- training reload makefile: default to onnx and tf conversions
  for all models (tf for training and onnx for inference)
  instead of tf-serving export

16943f70b4 models (ViT backbone) iterate extract_patches over batch dim… 
`Patches.call`: use `tf.map_fn` instead of running
entire batch through `tf.image.extract_patches`
(faster, less VRAM, allows ONNX conversion to work)

01e69a0e22 predictor for OCR models: work around ONNX bug … 
(ONNX converted models already return `np.dtype=object`
 arrays of `np.str_` instead of `np.bytes_`; so undo this)

948d841a7d training.models for cnn-rnn-ocr: make ONNX convertible… 
- `training.models.CTCDecoder`: switch back
  from `tf.nn.ctc_beam_search_decoder()`
  to `tf.nn.ctc_greedy_decoder()`
  (because ONNX only implements `CTCGreedyDecoder`)
- `training.models.cnn_rnn_ocr_model(inference=True)` and
  `training.models.cnn_rnn_ocr_model4inference`:
  drop layer `tf.io.decode_raw()`
  (because ONNX does not implement `DecodePaddedRaw`)
- `Eynollah_ocr.run_cnn()`: expect bytes arrays from predictor
  instead of uint8
- `predictor`: to prevent segfaults when sending `tf.string` results
  via `shared_memory`, convert `np.object` to `np.bytes_` directly

when rebuilding the inference model for cnn-rnn-ocr,
- open the old `characters_org.txt` file for the charset
- use it to pass the actual `n_classes` (overriding the config)
- use its path to pass the `characters_txt_file` (overriding the config)
