Detailed Description

Parsed representation of a string key that represents fitting of a product of space1 and space2 into fspace.

kernel must be parsable by ParsedTwoBodyOperSetKey.

The key format is (s1 s2|L(K)|f), where:

s1 = space1 label
s2 = space2 label
L = DF or RI, the latter returns coefficients scaled by inverse square root of the fitting kernel; if the fitting kernel is negative definite, will use the inverse square root of the negative.
K = fitting kernel label
f = fspace label
