fix: Use memcpy() in minitar_strlcpy()
...
This allows the platform to provide a more optimized and FAST version of memcpy than
our manual implementation inside strlcpy.

Do not automatically read an entry's contents, leave it up to the user
...
This API change modifies minitar_read_entry to skip over the file's contents and instead store the current read position in the entry.
struct minitar_entry no longer has a ptr field, but has a position field (of type fpos_t) for internal use.
minitar_free_entry no longer frees entry->ptr.
A new function has been added, minitar_read_contents().
It reads a certain number of bytes from an entry (which is capped to the entry's size) into a user-provided buffer.
This function can be called at any time provided it is called with a valid archive stream and entry.
This is achieved by calling fgetpos() to store the start of the entry's contents in the entry's position field while reading it.
Then minitar_read_contents() will store the current position, rewind to the entry's position, read the chosen number of bytes from the archive, and then rewind back to the current position.
Since this is a breaking change, it needs a major version bump. Since there was no version, I bumped it to 1.0.0 :)
