afae9e69ff Fix AxiStreamFrame default for self.byte_lanes from 1 to all. 
If I connect a AXIS source to an AXIS sink, the #byte_lanes is incorrectly 1 rather than all lanes enabled.
self.source = AxiStreamSource(AxiStreamBus.from_prefix(dut, "sink"), dut.clk, dut.reset)

Root cause is AxiStreamFrame assumes byte width 1 without TKEEP, but it should default to self.width // 8
because the AXIS specification mentions "when TKEEP is absent, TKEEP defaults to all bits HIGH" and "The width of the data payload is an integer number of bytes."

Fix: https://github.com/alexforencich/cocotbext-axi/blob/master/cocotbext/axi/axis.py#L290

self.byte_lanes = 1
self.byte_lanes = self.width // 8

Relevant AXIS Specification:

cde2056bb0 Remove deprecated <= assignments 
Starting from cocotb v1.6 the use of <= syntax has been deprecated. This
commit replaces all use of this syntax with the ``.value =`` syntax.
