Lazy Expression compiles successfully but will fail on execution

[lshaw8317]

Describe the bug
One can generate a lazy expression which is invalid due to operand data types, but this is not manifested until one tries to compute.

To Reproduce

import blosc2
N = 1_000
dtype = 'float64'

a = blosc2.linspace(0, 1, N * N, dtype=dtype, shape=(N, N))
b = blosc2.linspace(1, 2, N * N, dtype=dtype, shape=(N, N))
le1 = a + 2
le2 = le1 & (b < 0) #Does not fail
le2.compute() #Does fail

Expected behavior
Perhaps when checking/validating the expression, one should perform some additional checks, and the lazy expression does not generate successfully.

This is a separate issue to the chaining of lazy expressions, it relates to differing data types of operands.
