Each of the different commands that the "json-writer" helper accepts pops the next space-delimited token from the current line and interprets it as a string, integer, or double (with the exception of the very first token, which is the command itself). To accommodate this, split the line in place by the space character, and pass the corresponding string_list to each of the specialized `get_s()`, `get_i()`, and `get_d()` functions. `get_i()` and `get_d()` are thin wrappers around `get_s()` that convert their result into the appropriate type by either calling `strtol()` or `strtod()`, respectively. In `get_s()`, we mark the token as "consumed" by incrementing the `consumed_nr` counter, indicating how many tokens we have read up to that point. Because each of these functions needs the string-list parts, the number of tokens consumed, and the line number, these three are wrapped up in to a struct representing the line state.
