Air conditioner codes typically have 100 pulse/space pairs (12 bytes +
headers). The resulting raw IR line length is 1063, which exceeds the
current 1024 byte buffer, and results in an error trying to parse the
line.
The buffers used to read pulse/space files are significantly larger than
needed so this decreases their size, and allocates the difference to the
buffer used to read raw IR files in order to keep the total size of
buffers the same.
