Describe the doc issue

There are a few typos in the FaceRecognizerSF class documentation which make the underlying APIs difficult to interpret.

For example,

• For the alignCrop method the description reads:

  • @brief Aligning image to put face on the standard position.
  • It is unclear what is meant by standard position.

• For the match method the description for the dis_type parameter has a typo:

  • defining the similarity with optional values "FR_OSINE" or "FR_NORM_L2"
  • FR_OSINE --> FR_COSINE

Fix suggestion

For the alignCrop method:

/** @brief Aligns detected face with the source input image

For the match method

* @param dis_type defines how to calculate the distance between two face features with optional values "FR_COSINE" or "FR_NORM_L2"
