fix: updated merge/hybrid mining percentages to reflect 50/50 split (#…

…153)

Description
---
Corrected references in RFC 001 and RFC-0131 to reflect accurate split
in terms of merge mining and hybrid mining stated percentages.

Motivation and Context
---
RFCs were still referencing a 60/40 split, which is inaccurate.

 #### Proof of Work
 
-Tari is mined using a hybrid approach. On average, 60% of block rewards come from [Monero merge-mining],
- while 40% come from the [Sha3x][RFC-131] algorithm. Blocks are produced every 2 minutes, on average.

 a low likelihood of unforeseen optimizations that will give a single miner a considerable advantage. It also means that it stands a 
 good chance of being "commoditized" when ASICs are eventually manufactured. This would mean that SHA3 ASICs are widely available from multiple suppliers.
 
-### The block distribution

-A 50/50 split in hash rate among algorithms minimises the chance of hash rate attacks. However,
-sufficient buy-in is required, especially with regard to merge mining RandomX with Monero. To make it worthwhile for a
-Monero pool operator to merge mine Tari, but still guard against hash rate attacks and to be inclusive of independent
-Tari supporters and enthusiasts, a 60/40 split is employed in favour of merge mining RandomX with Monero.

 ### The difficulty adjustment strategy
 
 The choice of difficulty adjustment algorithm is important. In typical hybrid mining strategies, each algorithm operates
 completely independently with a scaled target block time.
