feat: priority recompute restructure

[pratikmishra356]

Problem

User has to declare this exponential value, as value is exponential it has limitation on the total number of dimensions that can be defined

Solution

Postgresql's Numeric Type Approach

For dimension we can have another column named order which will store order of dimension's specificity ,
the higher order is means more specific
For context , we will have another column named weightage , where we will calculate the value just like we do now
it will summation of (2^ dimension's order value)

since context's weightage value can be too large , so we will use postgresql Numeric type

CREATE TABLE large_numbers (
id SERIAL PRIMARY KEY,
big_value NUMERIC
);
Rust/ Diesel supports BigDecimal type which is compatible with Numeric type
