[NQM] "where"-like methods with several conditions

[MikitaBf]

Describe SQL method
.where_all() method accepts several conditions as kwargs and checks whether all of the conditions are True. Example: cur.select(...).where_all(condition_1=value_1, condition_2=value_2, ...)

(from the previous example onwards cur is an object of fyCursor)

.where_any() method accepts several conditions as kwargs and checks whether at least one of these conditions is True. Example:
cur.select(...).where_any(condition_1=value_1, condition_2=value_2, ...)

(Optional) Describe how you'd like to implement this method
All conditions passed to where_all() are connected with AND keyword, while where_any() connects them with OR.

Examples:

cur.select("name", "table").where_all(balance=100, level=2)

executes following SQL query:
"SELECT name FROM table WHERE balance = 100 AND level = 100"

The same syntax but with .where_any method executes a similar SQL query but with OR keyword.

(Optional) Additional context
As those methods accept kwargs, the following syntax is also allowed:

.where_all({"cond_1": val_1, ...})
.where_any({"cond_1": val_1, ...})
