feat(matrix): (1) Tolerate coord input like [['x1', 'x2', 'x3'], ...], where 'x1' and 'x3' is considered the range boundary. (2) Disable the default clamp in `matrix.body/corner.data[i].coord`, because it consider the illegal input as "refer to the entire row/column", which is more likely to mislead users and no error message. Introduce option `matrix.body/corner.data[i].coordClamp` to enable it.
