Primitive data types

There are several data types predefined in Kaitai Struct, thus they are used as basic building blocks for more complex data types:

Integers

Generally, integer type specification follows this pattern: ([us])(1|2|4|8)(le|be)

First letter — u or s — specifies either unsigned or signed integer respectively
Second group — 1, 2, 4 or 8 — specifies width of an integer in bytes
Third group — le or be — specifies little-endian or big-endian encoding respectively; it can be omitted if default endianness specified in meta.endianness in file description.

For the sake of completeness, here's the full table of available integer types:

`type`	Width, bits	Signed?	Endianness	Min value	Max value
`u1`	8	No	N/A	0	255
`u2le`	16	No	Little	0	65535
