fct_encode_one_hot

<code>fct_encode_one_hot()</code> encodes a factor as a one-hot indicator matrix.
This matrix consists of <code>length(x)</code> rows and <code>length(levels(x))</code> columns.
Every value in row <code>i</code> of the matrix is filled with <code>0L</code> except for the
column that has the same name as <code>x[[i]]</code>, which is instead filled with <code>1L</code>.

Building modeling packages is hard. A large amount of effort
generally goes into providing an implementation for a new method that
is efficient, fast, and correct, but often less emphasis is put on the
user interface. A good interface requires specialized knowledge about
S3 methods and formulas, which the average package developer might not
have. The goal of 'hardhat' is to reduce the burden around building
new modeling packages by providing functionality for preprocessing,
predicting, and validating input.
