Tidy a sparse matrix

sparse_matrix_to_tidy(
  sparse_mat,
  rows_id = "x",
  cols_id = "y",
  values_id = "value",
  keep_values = TRUE
)

`sparse_mat`	Sparse matrix of class `dgCMatrix` or its variants
`rows_id`	What is stored in the rows of matrix
`cols_id`	What is stored in the columns on matrix
`values_id`	What the values in the cells are
`keep_values`	Do you want to keep the values of the cells or is the matrix a binary one where just existance matters?

Tidy df with a row for each non-empty entry in the sparse matrix. If keep_values == TRUE then there will be a third column containing the value of cell in matrix at pairing.
