ClickHouse dialect should limit the Precision and Scale of the Decimal type to be within 76

Currently ClickHouse Dailect can not support accurate precision

In ClickHouse:

• P - precision. Valid range: [ 1 : 76 ]. 
• S - scale. Valid range: [ 0 : P ]. 

Depending on P parameter value Decimal(P, S) is a synonym for:

• P from [ 1 : 9 ] - for Decimal32(S)
• P from [ 10 : 18 ] - for Decimal64(S)
• P from [ 19 : 38 ] - for Decimal128(S)
• P from [ 39 : 76 ] - for Decimal256(S)

we can refer to doc with: https://clickhouse.com/docs/sql-reference/data-types/decimal

eg：select cast(\"product_id\" as decimal(22,20)) from \"product\"

but transform to: SELECT CAST(`product_id` AS DECIMAL(19, 19)) FROM `foodmart`.`product`

this should be transform to:  SELECT CAST(`product_id` AS DECIMAL(22, 20)) FROM `foodmart`.`product`

because CK precision is from[1, 76] 

user case: 

if user want to cast to a decimal type such as :

select cast('1.322131231313123311312322' as DECIMAL(30,24)) from system.numbers limit 1;

should be a decimal number of 1.322131231313123311312322

but currently  calcite ClickHouse dialect can only cast to：1.322131231313123311

this would cause loss of precision.
