méthodes

Signature	Description
`init(source: bytes	io.IOBase)`
`tell()` → `int`	Returns the current byte offset within the stream
`seek(offset: int, whence: int)`	Moves the read cursor to the given offset using the specified whence
`remaining()` → `int`	Returns the number of unread bytes left in the stream
`read_u8()` → `int`	Reads an unsigned 8‑bit integer and returns it as int
`read_u16()` → `int`	Reads a big‑endian unsigned 16‑bit integer from the underlying byte source and advances the read cursor
`read_u16_le()` → `int`	Reads a little‑endian unsigned 16‑bit integer
`read_u32()` → `int`	Reads a big‑endian unsigned 32‑bit integer
`read_u32_le()` → `int`	Reads a little‑endian unsigned 32‑bit integer
`read_u64()` → `int`	Reads a big‑endian unsigned 64‑bit integer
`read_i8()` → `int`	Reads a signed 8‑bit integer
`read_i16()` → `int`	Reads a big‑endian signed 16‑bit integer
`read_i16_le()` → `int`	Reads a little‑endian signed 16‑bit integer
`read_i32()` → `int`	Reads a big‑endian signed 32‑bit integer
`read_fixed()` → `float`	16.16 fixed-point → float.
`read_f2dot14()` → `float`	2.14 fixed-point → float.
`read_bytes(n: int)` → `bytes`	Reads n bytes from the stream and returns them as bytes
`read_tag()` → `str`	Read a 4-byte ASCII tag (e.g.
`read_pascal_string()` → `str`	Read a Pascal-style length-prefixed string.
`read_cstring()` → `str`	Read a null-terminated C string.
