Correctly cast `name_length`
`buffer[i++]` is a `signed char` so this cast does not correctly handle
negative values. If a custom tag has a length greater than 128 then
`buffer[i++]` is negative and so the `(uint16_t)` cast will cast it to a large
unsigned integer. This causes an out-of-bound read when reading the tag name.

We need to cast `name_length` to a `uint8_t` first, then widen to a `uint16_t`.

Prevent out-of-bounds read when deserializing
We first serialize the total number of tags, then serialize each individual
tag. If we don't have enough space to serialize a particular tag we stop
serializing any remaining tags.

However, this causes an out-of-bounds read when deserializing because there are
less tags than expected. Just bail when there are too many tags to serialize.

Avoid integer cast issues when deserializing tags
`buffer` contains signed chars, so if a tag length is greater than 128 then it
is treated as a negative value when deserializing. The negative signed char is
then implicitly cast to a large unsigned integer. Explicitly cast the values to
signed chars

Avoid integer truncation when serializing tag lengths
A tag longer than 255 characters will be incorrectly serialized.
