better default config for Tesseract

[noajshu]

A pretty good choice of parameters for Tesseract is the following:

tesseract_decoder.tesseract.TesseractConfig(
    dem=dem,
    pqlimit=200000,
    det_beam=5,
    det_orders=tesseract_decoder.utils.build_det_orders(
        dem, num_det_orders=20, det_order_bfs=True, seed=2384753),
    no_revisit_dets=True,
)

However, if we just create a Config it is implicitly using I think 1 det order, no_revisit_dets=False no beam, and a huge pqlimit (I think?)

To make it more user friendly, could we try to adapt these as default arguments?
